X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=2902bc66fa7a6d959e033e5358fd836e2839b5db;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

net: ethernet: micrel: fix an error code

The dma_mapping_error() function returns true or false.  We should
return -ENOMEM if it there is a dma mapping error.
