Subject: arm:i2c: Don't mask return from i2c_recv()
X-Git-Tag: v4.0.0-rc0~68^2~16
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=05f9f17e2caf249e9454f43e0c3751b2d06e1c06;p=thirdparty%2Fqemu.git

arm:i2c: Don't mask return from i2c_recv()

It can't fail, and now that it returns a uint8_t a 0xff mask
is unnecessary.
