3396995f - gpio: ljca: Initialize num before accessing item in ljca_gpio_config

Tue, 03 Dec 2024 14:14:51 +0000

gpio: ljca: Initialize num before accessing item in ljca_gpio_configWith the new __counted_by annocation in ljca_gpio_packet, the "num"struct member must be set before accessing the "item" array. Failing todo so will trigger a runtime warning when enabling CONFIG_UBSAN_BOUNDSand CONFIG_FORTIFY_SOURCE.Fixes: 1034cc423f1b ("gpio: update Intel LJCA USB GPIO driver")Cc: stable@vger.kernel.orgSigned-off-by: Haoyu Li Link: https://lore.kernel.org/stable/20241203141451.342316-1-lihaoyu499%40gmail.comSigned-off-by: Bartosz Golaszewski List of files: /linux-6.15/drivers/gpio/gpio-ljca.c

cdd30ebb - module: Convert symbol namespace to string literal

476f18c0 - gpio: ljca: use devm_mutex_init() to simplify the error path and remove()

Tue, 08 Oct 2024 16:24:16 +0000

gpio: ljca: use devm_mutex_init() to simplify the error path and remove()Destroying the mutexes is done at the end of remove() so switching todevres does not constitute a functional change. Use devm_mutex_init()and remove repetitions of mutex_destroy().Reviewed-by: Linus Walleij Link: https://lore.kernel.org/r/20241008162416.85111-1-brgl@bgdev.plSigned-off-by: Bartosz Golaszewski List of files: /linux-6.15/drivers/gpio/gpio-ljca.c

da2ad5fe - gpio: ljca: Convert to platform remove callback returning void

Thu, 28 Sep 2023 07:06:51 +0000

gpio: ljca: Convert to platform remove callback returning voidThe .remove() callback for a platform driver returns an int which makesmany driver authors wrongly assume it's possible to do error handling byreturning an error code. However the value returned is ignored (apartfrom emitting a warning) and this typically results in resource leaks.To improve here there is a quest to make the remove callback returnvoid. In the first step of this quest all drivers are converted to.remove_new(), which already returns void. Eventually after all driversare converted, .remove_new() will be renamed to .remove().Trivially convert this driver from always returning zero in the removecallback to the void returning variant.Signed-off-by: Uwe Kleine-König Reviewed-by: Linus Walleij Signed-off-by: Bartosz Golaszewski List of files: /linux-6.15/drivers/gpio/gpio-ljca.c
