Subject: pinctrl: return -ENOMEM instead of -EINVAL for kasprintf() failure
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=1fb1f0540deae634d454f917e3d45c27b69521a8;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

pinctrl: return -ENOMEM instead of -EINVAL for kasprintf() failure

-ENOMEM is more suitable error code because kasprintf() fails
in case of memory shortage.
