Subject: mtd: nand: sunxi: Return on set_feature only when not ENOTSUPP
X-Git-Url: http://git.dujemihanovic.xyz/?a=commitdiff_plain;h=850bdafa503e2045a8e931ce601fd71dc33157cf;p=u-boot.git

mtd: nand: sunxi: Return on set_feature only when not ENOTSUPP

Return the error code of the set_features function only if
the error code is not ENOTSUPP. Otherwise, if this function
is not supported, it will return and fail to initialize the
NAND.
