Subject: fs: exfat: Flush node before put in read() callback
X-Git-Tag: v2025.07-rc1~44^2~6
X-Git-Url: http://git.openpandora.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=aeed1373724e862acec9fda972d352c9241ee901;p=pandora-u-boot.git

fs: exfat: Flush node before put in read() callback

Make sure the node is never dirty before being released, flush
the node first using exfat_flush_node() and only then release
the node using exfat_put_node(). This now matches the behavior
of exfat_fs_write() too.
