[PATCH 0/4] staging: r8188eu: remove unused code for RF_PATH_B

[Martin Kaiser]

It seems that the r8188eu driver uses only RF_PATH_A. Remove RF_PATH_B
handling in some places where it's certainly not used.

[PATCH 1/4] staging: r8188eu: remove constant parameter of phy_LCCalibrate_8188E

[Martin Kaiser]

The only caller of phy_LCCalibrate_8188E sets is2t to false.
Remove this parameter and resulting dead code.

[PATCH 2/4] staging: r8188eu: remove dead code for tx power tracking

[Martin Kaiser]

always false. Remove resulting dead code.

[PATCH v2 2/4] staging: r8188eu: remove dead code for tx power tracking

[Martin Kaiser]

The odm_TXPowerTrackingCallback_ThermalMeter_8188E contains code
for OFDM paths A and B. It seems that path B is not used, is2t is
always false. Remove resulting dead code.

Without the path B code, the ele_A and ele_C variables are set but
not used. They can be removed. With ele_A and ele_C gone, X and Y
are now set but no longer used. Remove them as well.

[PATCH v2 3/4] staging: r8188eu: remove constant parameter of odm_ConfigRFReg_8188E

[Martin Kaiser]

The only caller of odm_ConfigRFReg_8188E sets RF_PATH to RF_PATH_A.
Remove this parameter and use RF_PATH_A inside the function.

[PATCH v2 4/4] staging: r8188eu: remove constant variable eRFPath

[Martin Kaiser]

In the _PHY_SwChnl8192C function, eRFPath is always zero. Remove the
variable and use 0 in the code. Replace (enum rf_radio_path)0 with
RF_PATH_A.
