[PATCH v2 0/8] staging: r8188eu: SetHwReg8188EU() cleanups

[PATCH v2 0/8] staging: r8188eu: SetHwReg8188EU() cleanups

[Michael Straube]

This series removes some cases from the function SetHwReg8188EU()
and moves the functionality to the callers. This is part of the
ongoing effort to get rid of the unwanted hal layer.

Tested on x86_64 with Inter-Tech DMG-02.

v2:
Moved some code into functions.
The series is based on todays staging-testing.

[PATCH v2 1/8] staging: r8188eu: remove HW_VAR_RESP_SIFS from SetHwReg8188EU()

[Michael Straube]

SetHwReg8188EU() is called with HW_VAR_RESP_SIFS only in one place.
Remove the HW_VAR_RESP_SIFS case from SetHwReg8188EU() and call
rtw_write8() directly instead. This is part of the ongoing effort to
get rid of the unwanted hal layer.

[PATCH v2 2/8] staging: r8188eu: remove HW_VAR_MLME_DISCONNECT from SetHwReg8188EU()

[Michael Straube]

SetHwReg8188EU() is called with HW_VAR_MLME_DISCONNECT only from
functions in rtw_mlme_ext.c. Move the functionality into a static
function in rtw_mlme_ext.c and remove the HW_VAR_MLME_DISCONNECT case
from SetHwReg8188EU(). This is part of the ongoing effort to get rid
of the unwanted hal layer.

[Michael Straube]

The HW_VAR_RXDMA_AGG_PG_TH case in SetHwReg8188EU() just sets a
variable conditionally and then calls rtw_write8(). Set the variable
in the caller and call rtw_write8() directly. Move the functionality

[PATCH v2 6/8] staging: r8188eu: simplify if-else statement

[Michael Straube]

Simplify a nested if-else statement to a single if-else statement in
rtw_set_threshold(). This improves readability and allows us to
remove the local variable threshold.

v2: Better readable simplification.

[PATCH v2 7/8] staging: r8188eu: remove HW_VAR_TX_RPT_MAX_MACID from SetHwReg8188EU()

[Michael Straube]

The HW_VAR_TX_RPT_MAX_MACID case in SetHwReg8188EU() just calls
rtw_write8(). Remove HW_VAR_TX_RPT_MAX_MACID from SetHwReg8188EU() and
call rtw_write8() directly. Move the call to a new function to indicate
what it actually does. This is part of the ongoing effort to get rid of
the unwanted hal layer.
