Subject: [PATCH v4 0/3] rtl8723bs: Remove redundant atomic op and replace global io error var

This patch series optimizes the IO error counting logic of the rtl8723bs wireless
driver by removing redundant atomic_t operations (unnecessary for non-concurrent scenarios) and replacing the global continual_io_error variable with local error counting. The series is split into logical patches (per Greg KH's review comment)
to ensure each patch fulfills a single, clear purpose, which greatly improves
reviewability and future maintainability.

Patch Breakdown:
1. 0001: Add independent rtw_check_continual_io_error function (single responsibility, includes old function cleanup)
2. 0002: Use local error_count in sd_read32/sd_write32 (eliminate global dependency, remove atomic ops)
3. 0003: Remove redundant global continual_io_error variable (clean up struct)

Changelog from v3 to v4:
- Split the monolithic v3 patch into logical, single-purpose patches
- Fixed all coding style errors (trailing spaces, missing assignment spaces, indentation, blank line alignment)
- Added detailed, purpose-driven commit messages for each patch
- Added version changelog as required by kernel documentation
- Added this cover letter to explain the entire patch series
- Optimized the new check function to remove redundant ternary expression (more concise kernel style)

Thank you for your time and review!
