ipack/carriers/tpci200: Fix a double free in tpci200_pci_probe

2021-07-19T08:01:24Z

commit 9272e5d0028d45a3b45b58c9255e6e0df53f7ad9 upstream. In the out_err_bus_register error branch of tpci200_pci_probe, tpci200->info->cfg_regs is freed by tpci200_uninstall()-> tpci200_unregister()->pci_iounmap(..,tpci200->info->cfg_regs) in the first time. But later, iounmap() is called to free tpci200->info->cfg_regs again. My patch sets tpci200->info->cfg_regs to NULL after tpci200_uninstall() to avoid the double free.

ipack: Handle a driver without remove callback

2021-02-09T08:48:23Z

A driver that only consumes devm-managed resources might well have no remove callback. Additionally given that the device core ignores the return value of ipack_bus_remove() stop returning an error code.

ipack: Fail earlier for drivers without probe function

2021-02-09T08:48:12Z

A driver without a probe function isn't useful as it can never be used. Let registering such a driver fail already instead of failing every binding. This is only cosmetic as there is no ipack driver without a probe function.

treewide: replace '---help---' in Kconfig files with 'help'

2020-06-13T16:57:21Z

Since commit 84af7a6194e4 ("checkpatch: kconfig: prefer 'help' over '---help---'"), the number of '---help---' has been gradually decreasing, but there are still more than 2400 instances. This commit finishes the conversion. While I touched the lines, I also fixed the indentation. There are a variety of indentation styles found. a) 4 spaces + '---help---' b) 7 spaces + '---help---' c) 8 spaces + '---help---' d) 1 space + 1 tab + '---help---' e) 1 tab + '---help---' (correct indentation) f) 1 tab + 1 space + '---help---' g) 1 tab + 2 spaces + '---help---' In order to convert all of them to 1 tab + 'help', I ran the following commend: $ find . -name 'Kconfig*' | xargs sed -i 's/^[[:space:]]*---help---/\thelp/' Signed-off-by: Masahiro Yamada

Pull tty / serial driver updates from Greg KH: "Here is the "large" TTY and Serial driver update for 5.3-rc1. It's in the negative number of lines overall as we removed an obsolete serial driver that was causing problems for some people who were trying to clean up some apis (the mpsc.c driver, which only worked for some pre-production hardware that no one has anymore.)
