Ma KeandGreg Kroah-Hartman 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.
