Subject: [PATCH] net: realtek: r8169: remove redundant assignment to giga_ctrl

From: Colin Ian King <colin.king@...onical.com>

The variable giga_ctrl is being assigned to zero however this is
never read and hence the assignment is redundant, so remove it.
Cleans up clang warning:

drivers/net/ethernet/realtek/r8169.c:1978:3: warning: Value stored
to 'giga_ctrl' is never read
