Subject: [RFC PATCH 04/19] net: remove shadowed variable
Date: Thu, 6 Nov 2025 14:09:33 +0000 [thread overview]
Message-ID: <20251106140948.2894678-5-bruce.richardson@intel.com> (raw)
In-Reply-To: <20251106140948.2894678-1-bruce.richardson@intel.com>
The "mask" local variable shadowed a global definition. The local var
was only used on two lines as a temporary value to pass the return value
of one function as a parameter to another. Therefore, we can remove the
shadowing issue by removing the variable.
Fixes: 17a937baed3e ("net: add CRC AVX512 implementation")
