The pin array handled by sh_pfc_map_pins() may contain holes representing non- existing pins. We have to first count the valid pins in order to calculate the size of the memory to be allocated, then to skip over the non-existing pins when initializing the allocated arrays, and then to return the number of valid pins from sh_pfc_map_pins() instead of 0 on success.
As we have to touch devm_kzalloc() calls anyway, use more fitting devm_kcalloc() instead which additionally checks the array size. And since PINMUX_TYPE_NONE is #define'd as 0, stop re-initializing already zeroed out 'pmx->configs' array.

--- The patch is against the 'devel' branch of Linus W.'s 'linux-pinctrl.git' repo. This patch should be applied before my R8A7794 PFC support patch and before Laurent's patches removing non-existent GPIOs for R8A779[01], otherwise they would cause the kernel to hang while booting!
OK not applying this until ACKed by Laurent, and in the meantime I'm taking the three applied R8A7794 patches out of my tree again.
Thanks!
Can you please send these depending patches as a series with this patch as 1/4 and the three R8A7794 patches as 2,3,4/4? Thanks.
OK, will try to remember. But what about Lauren't 2 patches also dependent on this one?
Yours, Linus Walleij
