X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=f6b24caaf933a466397915a08e30e885a32f905a;p=GitHub%2Fexynos8895%2Fandroid_kernel_samsung_universal8895.git via-velocity: Fix velocity driver unmapping incorrect size. When a packet is greater than ETH_ZLEN, we end up assigning the boolean result of a comparison to the size we unmap. Signed-off-by: Dave Jones Signed-off-by: David S.
