[PATCH v3] staging: rtl8723bs: replace kzalloc/kmalloc+memcpy with kmemdup

Posted by Alexandru Hossu 1 month, 1 week ago

Replace open-coded alloc+memcpy patterns with kmemdup().
This simplifies the code and avoids manual size/copy handling.

Signed-off-by: Alexandru Hossu <hossu.alexandru@gmail.com>

v3:
  - Drop unrelated DT binding changes from v2.
  - Wrap long line reported by checkpatch.
