From bc7d21ca2c150ecb0153a901fa99733f960ea461 Mon Sep 17 00:00:00 2001 From: Colin Ian King Date: Tue, 10 Oct 2017 15:05:48 +0100 Subject: [PATCH] staging: wilc1000: replace redundant computations with 0 Shifting and masking strHostIfSetMulti->enabled is redundant since enabled is a bool and so all the shifted and masked values will be zero. Replace them with zero to simplify the code. Detected by CoverityScan, CID#1339458 ("Bad shift operation") and CID#1339506 ("Operands don't affect result").
