Ma Ke 88f275a1e9 pinctrl: single: fix potential NULL dereference in pcs_get_function() ...

commit 1c38a62f15e595346a1106025722869e87ffe044 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().
