Subject: [MTD] [OneNAND] Use the u_char instead of char in oobbuf
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=978cb38a296fceac82a8a757f6387d7ef2a21ac6;p=openwrt%2Fstaging%2Fblogic.git

[MTD] [OneNAND] Use the u_char instead of char in oobbuf

In function onenand_verify_oob, local variable oobbuf shall be unsigned char.

In the case of a value is >= 0x80, it's unequal in comparing the value in an unsigned char and signed char.
