Subject: smsc95xx: remove EEPROM loaded check
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=bcd218be5aebed94951a750b1d477aea86fb68ea;p=GitHub%2Fexynos8895%2Fandroid_kernel_samsung_universal8895.git

smsc95xx: remove EEPROM loaded check

The eeprom read & write commands currently check the E2P_CMD_LOADED_ bit is
set before allowing any operations.  This prevents any reading or writing
unless a correctly programmed EEPROM is installed.

This patch removes the check, so it is possible to program blank EEPROMS
via ethtool.
