Subject: [PATCH linux] e1000e: Delete redundant variable definitions

From: luo penghao <luo.penghao@....com.cn>

The local variable is not used elsewhere in the function

The clang_analyzer complains as follows:

drivers/net/ethernet/intel/e1000e/ptp.c:241:19 warning

Value stored to 'hw' during its initialization is never read
