Subject: i2c: imx_lpi2c: Fix error detection
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=40ad377c1619eb9b83d088a96f40b86a907c8c19;p=thirdparty%2Fu-boot.git

i2c: imx_lpi2c: Fix error detection

Testing an unisgned ivariable to be <= 0 will only detect the
case when it is 0. So correct this error test to a working version that
will behave as expected.
