Subject: [PATCH v3 2/4] staging: rtl8723bs: replace rtw_zmalloc with kzalloc
replaces the wrapper function rtw_zmalloc with kzalloc.
I reviewed all the call sites to determine the appropriate GFP flags:
- GFP_KERNEL: Used for initialization and configuration paths.
init/probe, config/setup
- GFP_ATOMIC: Used for critical real-time paths.
including interrupts, timer handler, region where spinlocks are held
