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

[Michael Straube]

RTL8188EU chips are 1T1R. This set removes some code that is valid
only for 1T2R and 2T2R chips.

Tested on x86_64 with Inter-Tech DMG-02.

[PATCH 1/4] staging: r8188eu: remove IS_1T1R, IS_1T2R, IS_2T2R macros

[Michael Straube]

In this driver RFType is RF_TYPE_1T1R, so only the macro IS_1T1R
returns true. Remove the macros and adjust related code accordingly.

[PATCH 2/4] staging: r8188eu: remove if test that is always true

[Michael Straube]

The test "if (pHalData->rf_type == RF_1T1R)" is always true in this
driver. Remove the test and the dead else arm.

[PATCH 3/4] staging: r8188eu: remove NumTotalRFPath from struct hal_data_8188e

[Michael Straube]

NumTotalRFPath is 1 in this driver and it is only used as exit condition
in for loops. Since NumTotalRFPath is always 1, all the loops have only a
single iteration. So we can remove the for loops and the NumTotalRFPath
variable.

[PATCH 4/4] staging: r8188eu: remove switches from phy_RF6052_Config_ParaFile()

[Michael Straube]

In function phy_RF6052_Config_ParaFile() the variable eRFPath is always 0
and RF_PATH_A = 0 in this driver. So we can remove the 'switch (eRFPath)'
statements and just keep the code from the RF_PATH_A cases.
