commit 94e7c844990f0db92418586b107be135b4963b66 upstream.
Clang warns when a variable is assigned to itself.
drivers/net/usb/lan78xx.c:940:11: warning: explicitly assigning value of variable of type 'u32' (aka 'unsigned int') to itself [-Wself-assign] offset = offset; ~~~~~~ ^ ~~~~~~ 1 warning generated.
Reorder the if statement to acheive the same result and avoid a self assignment warning.
