Hi Heinrich,
Looking at this function can we clean it up since you are touching it already?
I think it would look nicer if you defined a local variable of struct efi_device_path * and always assign it in the if cases.
Then at the bottom of the function, we could store the ptr value if that exists. While at it the 'if (!*file)' seems to be misplaced.
Regards /Ilias

According to our coding style guide #ifdef should be avoided. Use IS_ENABLED() instead.
Sort string comparisons alphabetically.
