X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=bf1f9ae05036e12035f8e9a48f3dcf4dd14fdada;p=GitHub%2FLineageOS%2FG12%2Fandroid_kernel_amlogic_linux-4.9.git

sis900: Fix mem leak in sis900_rx error path

Fix memory leak in error path of sis900_rx(). If we don't do this we'll
leak the skb we dev_alloc_skb()'ed just a few lines above when the
variable goes out of scope.
