Subject: qeth: Include error message for "OS Mismatch"
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=1b05cf6285c108c8c2acfec47dd02ed50d973823;p=GitHub%2FLineageOS%2FG12%2Fandroid_kernel_amlogic_linux-4.9.git

Having understood the semantics of BRIDGEPORT error code 0x0010,
we can introduce a meaningful error message.
