Hi Andy, Le 18/11/2024 à 13:31, Andy Shevchenko a écrit :
Remove legacy-of-mm-gpiochip.h header file. The above mentioned file provides an OF API that's deprecated. There is no agnostic alternatives to it and we have to open code the logic which was hidden behind of_mm_gpiochip_add_data(). Note, most of the GPIO drivers are using their own labeling schemas and resource retrieval that only a few may gain of the code deduplication, so whenever alternative is appear we can move drivers again to use that one. As a side effect this change fixes a potential memory leak on an error path, if of_mm_gpiochip_add_data() fails.
Is there a reason for having done this change in cpm1_gpiochip_add16() and cpm1_gpiochip_add32() [arch/powerpc/platform/8xx/cpm1.c] and not in cpm2_gpiochip_add32() [arch/powerpc/sysdev/cpm_common.c] while all three functions are called from cpm_gpio_probe() [arch/powerpc/sysdev/cpm_gpio.c] ?
