The platform_get_resource_byname() function returns NULL on error, it
doesn't return error pointers.

The commit message for commit d166a73503ef ("spi: fspi: dynamically
alloc AHB memory") is not very good. Why is it necessary to allocate
the AHB memory dynamically instead of during probe? Also I suspect that
Adam should have recieved authorship credit for that patch.
