From 1ad866e7bf1c64238d77aa5e390e90cf7a5c6c41 Mon Sep 17 00:00:00 2001 From: Larry Finger Date: Wed, 4 Sep 2013 15:56:05 -0500 Subject: [PATCH] staging: r8188eu: Fix smatch warnings in core/rtw_xmit.c Smatch reports the following: drivers/staging/rtl8188eu/hal/rtl8188e_hal_init.c:1500 hal_EfusePgPacketWriteData() info: ignoring unreachable code. drivers/staging/rtl8188eu/hal/rtl8188e_hal_init.c:2188 Hal_ReadTxPowerInfo88E() error: buffer overflow 'pHalData->Index24G_CCK_Base[rfPath]' 14 <= 14 drivers/staging/rtl8188eu/hal/rtl8188e_hal_init.c:2190 Hal_ReadTxPowerInfo88E() error: buffer overflow 'pHalData->Index24G_BW40_Base[rfPath]' 14 <= 14 drivers/staging/rtl8188eu/hal/rtl8188e_hal_init.c:2196 Hal_ReadTxPowerInfo88E() error: buffer overflow 'pHalData->Index24G_CCK_Base[rfPath]' 14 <= 14 drivers/staging/rtl8188eu/hal/rtl8188e_hal_init.c:2197 Hal_ReadTxPowerInfo88E() error: buffer overflow 'pHalData->Index24G_BW40_Base[rfPath]' 14 <= 14 The first of these is trivial. The rest are due to an off-by-one error in a loop over the channels.
