Subject: exfat: improve error code handling in exfat_find_empty_entry()
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=8ffe56b104c5a9cdb88e3c7b2d84fa70d8866e64;p=thirdparty%2Fkernel%2Fstable.git

exfat: improve error code handling in exfat_find_empty_entry()

Change the type of 'ret' from unsigned int to int in
exfat_find_empty_entry(). Although the implicit type conversion
(int -> unsigned int -> int) does not cause actual bugs in
practice, using int directly is more appropriate for storing
error codes returned by exfat_alloc_cluster().

This improves code clarity and consistency with standard error
handling practices.
