Subject: fs: exfat: Remove unused label code
X-Git-Tag: v2025.10-rc1~15
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=8f3820dc3a262b0d11c261bf3c526159d8c771e3;p=thirdparty%2Fu-boot.git

fs: exfat: Remove unused label code

Smatch reported a possible buffer overflow in exfat_set_label but it
turns out that this code is unused so just guard the function with
'#ifndef __UBOOT__' as well as exfat_get_label that is also unused and
the helper static find_label.
