Subject: Btrfs: remove unnecessary IS_ERR in bio_readpage_error()
X-Git-Url: http://git.cdn.openwrt.org/?a=commitdiff_plain;h=7a2d6a64645b38d7040bbd031c7a7b2655f5d976;p=openwrt%2Fstaging%2Fblogic.git

Btrfs: remove unnecessary IS_ERR in bio_readpage_error()

Because the value of extent_map is only a correct value or NULL,
so IS_ERR is unnecessary.
