mei: remove dev_err message on an unsupported ioctl

2018-04-08T12:29:49Z

commit bb0829a741792b56c908d7745bc0b2b540293bcc upstream. Currently the driver spams the kernel log on unsupported ioctls which is unnecessary as the ioctl returns -ENOIOCTLCMD to indicate this anyway. I suspect this was originally for debugging purposes but it really is not required so remove it. Signed-off-by: Colin Ian King Cc: stable Signed-off-by: Greg Kroah-Hartman

mei: set device client to the disconnected state upon suspend.

2018-02-16T10:16:40Z

This fixes regression introduced by commit 8d52af6795c0 ("mei: speed up the power down flow") In mei_cldev_disable during device power down flow, such as suspend or system power off, it jumps over disconnecting function to speed up the power down process, however, because the client is unlinked from the file_list (mei_cl_unlink) mei_cl_set_disconnected is not called from mei_cl_all_disconnect leaving resource leaking. The most visible is reference counter on underlying HW module is not decreased preventing to remove modules after suspend/resume cycles.

vfs: do bulk POLL* -> EPOLL* replacement

2018-02-11T22:34:03Z

This is the mindless scripted replacement of kernel use of POLL* variables as described by Al, done by this script: for V in IN OUT PRI ERR RDNORM RDBAND WRNORM WRBAND HUP RDHUP NVAL MSG; do L=`git grep -l -w POLL$V | grep -v '^t' | grep -v /um/ | grep -v '^sa' | grep -v '/poll.h$'|grep -v '^D'` for f in $L; do sed -i "-es/^$[^\"]*$$\$/\\1E\\2/" $f; done done with de-mangling cleanups yet to come. NOTE! On almost all architectures, the EPOLL* constants have the same values as the POLL* constants do. But they keyword here is "almost". For various bad reasons they aren't the same, and epoll() doesn't actually work quite correctly in some cases due to this on Sparc et al. The next patch from Al will sort out the final differences, and we should be all done. Scripted-by: Al Viro Signed-off-by: Linus Torvalds

Merge tag 'char-misc-4.16-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/char-misc

2018-02-01T18:31:17Z

Pull char/misc driver updates from Greg KH: "Here is the big pull request for char/misc drivers for 4.16-rc1. There's a lot of stuff in here. Three new driver subsystems were added for various types of hardware busses: - siox - slimbus - soundwire as well as a new vboxguest subsystem for the VirtualBox hypervisor drivers. There's also big updates from the FPGA subsystem, lots of Android binder fixes, the usual handful of hyper-v updates, and lots of other smaller driver updates. All of these have been in linux-next for a long time, with no reported issues" * tag 'char-misc-4.16-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/char-misc: (155 commits) char: lp: use true or false for boolean values android: binder: use VM_ALLOC to get vm area android: binder: Use true and false for boolean values lkdtm: fix handle_irq_event symbol for INT_HW_IRQ_EN EISA: Delete error message for a failed memory allocation in eisa_probe() EISA: Whitespace cleanup misc: remove AVR32 dependencies virt: vbox: Add error mapping for VERR_INVALID_NAME and VERR_NO_MORE_FILES soundwire: Fix a signedness bug uio_hv_generic: fix new type mismatch warnings uio_hv_generic: fix type mismatch warnings auxdisplay: img-ascii-lcd: add missing MODULE_DESCRIPTION/AUTHOR/LICENSE uio_hv_generic: add rescind support uio_hv_generic: check that host supports monitor page uio_hv_generic: create send and receive buffers uio: document uio_hv_generic regions doc: fix documentation about uio_hv_generic vmbus: add monitor_id and subchannel_id to sysfs per channel vmbus: fix ABI documentation uio_hv_generic: use ISR callback method ...

mei: fix an && vs || typo

2018-01-09T16:52:58Z

->dev_state can't be both MEI_DEV_RESETTING and MEI_DEV_POWER_DOWN at the same time. && was clearing intended here. Fixes: 8d52af6795c0 ("mei: speed up the power down flow") Signed-off-by: Dan Carpenter Signed-off-by: Greg Kroah-Hartman

mei: fix incorrect logical operator in if statement

2018-01-02T16:09:29Z

The current expression using the || operator is always true because dev->dev_state cannot be equal to two different values at the same time. Fix this by replacing the || with &&.

mei: me: allow runtime pm for platform with D0i3

2018-01-02T16:09:29Z

>From the pci power documentation: "The driver itself should not call pm_runtime_allow(), though. Instead, it should let user space or some platform-specific code do that (user space can do it via sysfs as stated above)..." However, the S0ix residency cannot be reached without MEI device getting into low power state. Hence, for mei devices that support D0i3, it's better to make runtime power management mandatory and not rely on the system integration such as udev rules. This policy cannot be applied globally as some older platforms were found to have broken power management. Cc: v4.13+ Cc: Rafael J.
