Subject: fs: fat: directory entries starting with 0x05
X-Git-Url: http://git.dujemihanovic.xyz/%7B%7B%20%24style.RelPermalink%20%7D%7D?a=commitdiff_plain;h=a2c5a92d4865cea53de8a9297a4f4d115e6ac3b6;p=u-boot.git

fs: fat: directory entries starting with 0x05

0x05 is used as replacement letter for 0xe5 at the first position of short
file names. We must not skip over directory entries starting with 0x05.

Cf. Microsoft FAT Specification, August 30 2005

Fixes: 39606d462c97 ("fs: fat: handle deleted directory entries correctly")
