Ma Ke 6341c28567 pinctrl: single: fix potential NULL dereference in pcs_get_function() ... commit 1c38a62f15 upstream. pinmux_generic_get_function() can return NULL and the pointer 'function' was dereferenced without checking against NULL. Add checking of pointer 'function' in pcs_get_function(). Found by code review.
