From ee82be77be24f6ea2508e5ad2d5ae559c08e7a6d Mon Sep 17 00:00:00 2001 From: Phillip Potter Date: Tue, 15 Jun 2021 23:36:03 +0100 Subject: [PATCH] staging: rtl8188eu: remove unused variables from core/rtw_efuse.c Remove set but unused variables from within the file core/rtw_efuse.c in the function efuse_read_phymap_from_txpktbuf, as they are triggering kernel test robot warnings. Also, remove the local 'lenc' array as well, as nothing is done with its values. Keep the two usb_read8 calls however, as this patch is purely for warnings, not to change behaviour of the code.
