[PATCH v1 2/2] gpiolib: Unify allocation and initialization of GPIO valid mask

From: Andy Shevchenko
Date: Sat May 27 2023 - 07:41:15 EST


Now that the of_gpiochip_add() doesn't use valid mask, we may
unify GPIO valid mask allocation and initialization. With this
it makes a symmetry to the similar which we done for IRQ chip.
