Thanks. Though I think it can be also applied to I²C tree since dependency? Any tags / immutable branch for Wolfram? -- With Best Regards, Andy Shevchenko

In that case: Acked-by: Bartosz Golaszewski <bgolaszewski@baylibre.com> Wolfram, please take it through the i2c tree. Bartosz

The usual pattern for the remove calls, like gpiod_remove_lookup_table(), is to be NULL-aware, i.o.w. become a no-op whenever parameter is NULL. Update gpiod_remove_lookup_table() call to follow this pattern. Signed-off-by: Andy Shevchenko <andriy.shevchenko@linux.intel.com> --- drivers/gpio/gpiolib.c | 4 ++++ 1 file changed, 4 insertions(+)
