Subject: sfc: Make efx_mcdi_init() call efx_mcdi_handle_assertion()
X-Git-Tag: accepted/tizen/common/20141203.182822~1569^2~104^2~64
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=f073dde03b3e8d11050d82f52caaf75fd924e069;p=platform%2Fkernel%2Flinux-arm64.git

sfc: Make efx_mcdi_init() call efx_mcdi_handle_assertion()

This should probably be done during MCDI initialisation for any NIC.
Change efx_mcdi_init() to return an error code.
