slimbus: fix a potential NULL pointer dereference in of_qcom_slim_ngd_register

2019-05-31T13:43:22Z

[ Upstream commit 06d5d6b7f9948a89543e1160ef852d57892c750d ] In case platform_device_alloc fails, the fix returns an error code to avoid the NULL pointer dereference. Signed-off-by: Kangjie Lu Signed-off-by: Srinivas Kandagatla Signed-off-by: Greg Kroah-Hartman Signed-off-by: Sasha Levin

slimbus: core: add missing spin_lock_init on txn_lock

2019-01-22T12:34:35Z

Add missing spin lock intialization this also fixes the spinlock bad magic warning. Signed-off-by: Srinivas Kandagatla Signed-off-by: Greg Kroah-Hartman

slimbus: core: use slim_device_update_status() to update status

2019-01-22T12:34:35Z

use slim_device_update_status() instead of directly calling the device_status() callback. Move slim_device_update_status() before probe to avoid forward declaration too. Signed-off-by: Srinivas Kandagatla Signed-off-by: Greg Kroah-Hartman

slimbus: core: do not call device_status under a lock

2019-01-22T12:34:34Z

Calling device_status callback under a lock would prevent drivers to do any slimbus trasactions which would invoke this lock like get_laddr(). Remove this unnecessary lock! Signed-off-by: Srinivas Kandagatla Signed-off-by: Greg Kroah-Hartman

slimbus: core: match full device id

2019-01-22T12:34:34Z

match full slim device id instead of just product and manufacture code, this will allow drivers to be much more specific to that device. Signed-off-by: Srinivas Kandagatla Signed-off-by: Greg Kroah-Hartman

slimbus: ngd: fix spelling mistake "exeeds" -> "exceeds"

2018-12-06T14:50:06Z

There is a spelling mistake in a dev_err message, fix this. Signed-off-by: Colin Ian King Signed-off-by: Srinivas Kandagatla Signed-off-by: Greg Kroah-Hartman

slimbus: qcom-ctrl: simplify getting .driver_data

2018-12-06T14:50:05Z

We should get 'driver_data' from 'struct device' directly. Going via platform_device is an unneeded step back and forth. Signed-off-by: Wolfram Sang Signed-off-by: Srinivas Kandagatla Signed-off-by: Greg Kroah-Hartman

slimbus: ngd: QCOM_QMI_HELPERS has to be selected

2018-11-27T07:44:06Z

QCOM_QMI_HELPERS is a hidden kconfig, so the proper usage is to select it, not depend upon it. Because of this change, we now also need to depend on the same Kconfigs as QCOM_QMI_HELPERS depends on. Signed-off-by: Niklas Cassel Signed-off-by: Srinivas Kandagatla Signed-off-by: Greg Kroah-Hartman

slimbus: ngd: Fix build error on x86

2018-11-27T07:44:06Z

on non DT platforms like x86 of_match_node is set to NULL, dereferencing directly would throw an error. Fix this by doing this in two steps, get the match then the data. Reported-by: Greg KH Signed-off-by: Srinivas Kandagatla Signed-off-by: Greg Kroah-Hartman

slimbus: ngd: remove unnecessary check

2018-11-07T13:59:28Z

SLIM_MSG_CLK_PAUSE_SEQ_FLG is never set in any of the slim core, so performing a check in ngd driver is totally unnecessary. Also this patch fixes warning about mc field overflow reported with CoverityScan. Making clk pause feature optional will be added to slim core in next development cycle.
