Subject: i40e: remove redundant initialization of read_size
Patch-mainline: v4.16-rc1
Git-commit: 793c6f8c85d6d8cc6aa9cd68ee3552d2591f30e0
References: bsc#1101816 FATE#325147 FATE#325149
Variable read_size is initialized and this value is never read, it is
instead set inside the do-loop, hence the initialization is redundant
and can be removed. Cleans up clang warning:
drivers/net/ethernet/intel/i40e/i40e_nvm.c:390:6: warning: Value stored
to 'read_size' during its initialization is never read
