Subject: [PATCH 6/6] staging: r8188eu: refactor dm func set and clear
Refactor the code to set and clear "dm functions".
The only remaining callers of Switch_DM_Func use
Switch_DM_Func(padapter, DYNAMIC_ALL_FUNC_ENABLE, true) or
Switch_DM_Func(padapter, DYNAMIC_FUNC_DISABLE, false).
Remove Switch_DM_Func and call SetHwReg8188EU directly.
For HW_VAR_DM_FUNC_SET, the parameter is always DYNAMIC_ALL_FUNC_ENABLE.
This operation resets podmpriv->SupportAbility to the initial value.
Rename HW_VAR_DM_FUNC_SET to HW_VAR_DM_FUNC_RESET and drop the unused
else branch.
For HW_VAR_DM_FUNC_CLR, the parameter is always DYNAMIC_FUNC_DISABLE
(0x00). We can set podmpriv->SupportAbility to 0 directly.
