[PATCH 5.4 13/65] igc: set the default return value to -IGC_ERR_NVM in igc_write_nvm_srwr

[Greg Kroah-Hartman]

From: Kevin Lo <kevlo@xxxxxxxxx>

[ Upstream commit ebc8d125062e7dccb7922b2190b097c20d88ad96 ]

This patch sets the default return value to -IGC_ERR_NVM in
igc_write_nvm_srwr. Without this change it wouldn't lead to a shadow RAM
write EEWR timeout.

Fixes: ab4056126813 ("igc: Add NVM support")
