Subject: [PATCH v5 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)

Thank you for your time and review!

Changelog from v1 to v2:
Initial draft: Implemented basic local error count logic, fixed compilation errors.

Changelog from v2 to v3:
Merged small patches into one, optimized function logic to remove redundant code.

Changelog from v3 to v4:
Split monolithic patch into single-purpose patches (per Greg's comment), fixed coding style.

Changelog from v4 to v5:
Fixed format errors (spaces around '=', trailing whitespace) per checkpatch.pl;
Standardized author name format (split "changjunzheng" to "Changjun Zheng");
Moved changelog to below the --- separator (kernel format rule).
