2025-02-24input: ipaq-micro-keys: use devm_kmemdup_array()Raag Jadav
Convert to use devm_kmemdup_array() which is more robust. Signed-off-by: Raag Jadav <raag.jadav@intel.com> Reviewed-by: Linus Walleij <linus.walleij@linaro.org> Signed-off-by: Andy Shevchenko <andriy.shevchenko@linux.intel.com>
2024-10-03Input: ipaq-micro-keys - use guard notation when acquiring mutex and spinlockDmitry Torokhov
This makes the code more compact and error handling more robust by ensuring that locks are released in all code paths when control leaves critical section. Link: https://lore.kernel.org/r/20240825051627.2848495-8-dmitry.torokhov@gmail.com Signed-off-by: Dmitry Torokhov <dmitry.torokhov@gmail.com>
2023-12-03Input: ipaq-micro-keys - add error handling for devm_kmemdupHaoran Liu
Check the return value of i2c_add_adapter. Static analysis revealed that the function did not properly handle potential failures of i2c_add_adapter, which could lead to partial initialization of the I2C adapter and unstable operation.

2022-12-07Input: ipaq-micro-keys - switch to DEFINE_SIMPLE_DEV_PM_OPS() and pm_sleep_ptr()Jonathan Cameron
SIMPLE_DEV_PM_OPS() is deprecated as it requires explicit protection against unused function warnings. The new combination of pm_sleep_ptr() and DEFINE_SIMPLE_DEV_PM_OPS() allows the compiler to see the functions, thus suppressing the warning, but still allowing the unused code to be removed. Thus also drop the __maybe_unused markings.
