[PATCH v2 0/6] staging: rtl8192e: Remove enum RF_1T2R and useless cases for customer_id

[Philipp Hortmann]

Remove enum RF_1T2R as the code using it has always the same result.
Remove useless cases for customer_id.

Tested with rtl8192e
Transferred this patch over wlan connection of rtl8192e
---
V1->V2: Added first patch to avoid a useage of an uninitialized
        variable RF_Type introduced by later patches.

[PATCH v2 1/6] staging: rtl8192e: Remove RF_Type from .._dm_tx_update_tssi_weak_signal

[Philipp Hortmann]

Remove RF_Type from _rtl92e_dm_tx_update_tssi_weak_signal and
_rtl92e_dm_tx_update_tssi_strong_signal as it is unused.

Reported-by: kernel test robot <lkp@intel.com>

---
V1->V2: This patch did not exist before and was added because RF_Type
        was used here but left uninitialized by later patches.

[PATCH v2 2/6] staging: rtl8192e: Remove enum RF_1T2R and RF_Type

[Philipp Hortmann]

enum RF_1T2R is used to initialize a local variable RF_Type that is then
shifted. The result of the shift is zero. Remove code that has always
the same result to increase readability.
