Subject: net: pch_gbe: Remove reset_phy HAL abstraction
X-Git-Tag: v4.19-rc1~140^2~559^2~9
X-Git-Url: http://git.osdn.net/view?a=commitdiff_plain;h=7dbe38aed0ba01e9557621d7e6d59c5b92decead;p=uclinux-h8%2Flinux.git

net: pch_gbe: Remove reset_phy HAL abstraction

For some reason the pch_gbe driver contains a struct pch_gbe_functions
with pointers used by a HAL abstraction layer, even though there is only
one implementation of each function.

This patch removes the reset_phy abstraction in favor of calling
pch_gbe_phy_hw_reset directly.
