[PATCH 00/29] tty: cleanup no. 99

by Jiri Slaby (SUSE)

Hi, this is (again) a series of cleanup in tty. I am trying to rework tty+serial to avoid limitations of devices (so called NR_UART or tty_alloc_driver()'s first parameter). And the below popped up while crawling through the code. So this is only a prep cleanup. * many tty flags are now enums * many functions were improved for readability * quite a few unused or old code dropped In particular, the runtime behaviour of the kernel before and after the changes is supposed to be bug to bug compatible (except moxa's ioctl and ISA evils dropped). That is, noone should notice.

[PATCH 00/34] address all -Wunused-const warnings

by Arnd Bergmann

From: Arnd Bergmann <arnd(a)arndb.de> Compilers traditionally warn for unused 'static' variables, but not if they are constant. The reason here is a custom for C++ programmers to define named constants as 'static const' variables in header files instead of using macros or enums. In W=1 builds, we get warnings only static const variables in C files, but not in headers, which is a good compromise, but this still produces warning output in at least 30 files. These warnings are almost all harmless, but also trivial to fix, and there is no good reason to warn only about the non-const variables being unused. I've gone through all the files that I found using randconfig and allmodconfig builds and created patches to avoid these warnings, with the goal of retaining a clean build once the option is enabled by default. Unfortunately, there is one fairly large patch ("drivers: remove incorrect of_match_ptr/ACPI_PTR annotations") that touches 34 individual drivers that all need the same one-line change. If necessary, I can split it up by driver or by subsystem, but at least for reviewing I would keep it as one piece for the moment. Please merge the individual patches through subsystem trees. I expect that some of these will have to go through multiple revisions before they are picked up, so anything that gets applied early saves me from resending.

[PATCH] staging: greybus: remove unnecessary parentheses

by Will Walsh

Unnecessary parentheses in boolean comparisons make it harder to read. Removed the extra parentheses on line 305 for code readability.

[PATCH] staging: greybus: Remove module from list before freeing in gb_audio_module_release

by Atharva Tiwari

Previously,the module was freed without detaching it from the list which could lead to memory leak this patch uses list_del to safely remove the module from the list Signed-off-by: Atharva Tiwari <evepolonium(a)gmail.com> --- drivers/staging/greybus/audio_manager_module.c | 3 ++- 1 file changed, 2 insertions(+), 1 deletion(-) diff --git a/drivers/staging/greybus/audio_manager_module.c b/drivers/staging/greybus/audio_manager_module.c index 4a4dfb42f50f..7e52c3f95692 100644 --- a/drivers/staging/greybus/audio_manager_module.c +++ b/drivers/staging/greybus/audio_manager_module.c @@ -69,7 +69,8 @@ static void gb_audio_module_release(struct kobject *kobj) struct gb_audio_manager_module *module = to_gb_audio_module(kobj); pr_info("Destroying audio module #%d\n", module->id); - /* TODO -> delete from list */ + if (module->list.prev && module->list.next) + list_del(&module->list); kfree(module); } -- 2.39.5

[PATCH v3] staging: greybus: uart: Fix atomicity violation in get_serial_info()

by Qiu-ji Chen

Our static checker found a bug where set_serial_info() uses a mutex, but get_serial_info() does not. Fortunately, the impact of this is relatively minor. It doesn't cause a crash or any other serious issues. However, if a race condition occurs between set_serial_info() and get_serial_info(), there is a chance that the data returned by get_serial_info() will be meaningless. Signed-off-by: Qiu-ji Chen <chenqiuji666(a)gmail.com> Fixes: 0aad5ad563c8 ("greybus/uart: switch to ->[sg]et_serial()") --- V2: Modified the patch description to make it more concise and easier to understand. Changed the fix code to ensure the logic is correct. Thanks to Johan Hovold and Dan Carpenter for helpful suggestion. V3: Used the correct patch prefix.
