[PATCH 00/61] staging: rtl8723bs: monolithic HAL cleanup and tx power limit fix

[Arsenii Pashchenko <ulijg308@gmail.com>]

Hello,

This patch series performs a massive, systematic cleanup of the legacy 
vendor HAL layer and redundant abstraction wrappers in the rtl8723bs 
driver, concluding with a functional fix for the TX power limit lookup.

The primary goal of this refactoring is to drastically improve the 
readability and maintainability of the codebase, transforming the 
highly tangled, Windows-legacy Realtek abstractions into a cleaner, 
more idiomatic Linux driver structure.

KEY CHANGES IN THIS SERIES:

1. Dead Code & Stub Removal: Eliminated several unimplemented functions, 
   empty stubs (like OnAtim, DoReserved), duplicate prototypes, and 
   completely unused helpers (NULL_hdl, set_csa_hdl, tdls_hdl).
2. Wrapper Collapse & Inlining: Removed multiple layers of superficial 
   wrappers around core operations (e.g., rtw_ap_set_group_key, 
   issue_deauth, issue_probereq, rtw_free_mlme_priv, etc.). High-frequency 
   or single-use HAL entry points (like SetHwReg8723BS, GetHwReg8723BS, 
   and xmit helpers) have been carefully inlined directly into their 
   respective dispatchers to enhance readability.
3. Scope & Warning Fixes: Restructured local functions (like 
   lps_ctrl_wk_hdl) by marking them static and aligning headers, which 
   resolves missing-prototypes compiler warnings.
4. Logical Fixes: In the final patch, a critical copy-paste bug in 
   phy_get_tx_pwr_lmt() was resolved. The computed channel index from 
   phy_GetChannelIndexOfTxPowerLimit() was mistakenly assigned back to 
   the 'channel' parameter and discarded, leaving 'idx_channel' at -1. 
   This caused the function to always fail validation and return 
   MAX_POWER_INDEX. Correcting this restores the intended hardware tx 
   power limit logic and resolves a compiler warning.
5. Refined Abstractions: In places where removing a wrapper would 
   decrease overall elegance or require awkward type workarounds, the 
   cleanest architectural approach was intentionally preserved.

TESTING & VERIFICATION:

- Hardware: I do not possess the physical rtl8723bs hardware, so 
  real-world runtime wireless testing was not performed.
- Compilation: The entire series compiles flawlessly against the 
  latest tree.
- Code Style: All 61 patches have been fully validated with 
  `scripts/checkpatch.pl` and return 0 errors / 0 warnings per patch. 
  (Note: A few pre-existing vendor style warnings remain in the modified 
  files, but no new ones were introduced).

This cleanup significantly reduces the boilerplate footprint, making 
future maintenance and eventual mac80211 migration tasks much more 
approachable.

Please review.

Thanks,
Arsenii
