[PATCH 0/7] staging: rtl8723bs: remove unnecessary void pointer casts

[Siwanan Bungtong]

This series removes redundant (void *) casts across rtl8723bs.

C automatically converts pointers to void *, so these casts are
unnecessary and add noise. Removing them improves readability and
follows kernel style guidelines.

No functional changes.

[PATCH 1/7] staging: rtl8723bs: rtw_ap: remove unnecessary void * casts

[Siwanan Bungtong]

Remove redundant (void *) casts when calling memcpy/memset and
other helpers. These casts are unnecessary since C implicitly
converts to void * and they only add noise.

No functional change.

No, for this type of series, the filename makes sense.  The subjects
would not be unique otherwise.
