A recent refactoring to use the func member in struct function_desc missed converting one uses of name in keembay_build_functions(), resulting in a build failure: drivers/pinctrl/pinctrl-keembay.c: In function 'keembay_build_functions': drivers/pinctrl/pinctrl-keembay.c:1630:35: error: 'struct function_desc' has no member named 'name' 1630 | if (!fdesc->name) { | ^~ Perform the same conversion to resolve the build error.
