[PATCH v2] staging: rtl8723bs: split chained assignments in _rtw_open_pktfile()
Posted by Godana Emiru 3 weeks, 4 days ago
Fix a checkpatch CHECK ("multiple assignments should be avoided") by
splitting the two chained assignments into separate statements.

Assign cur_addr and buf_start directly from pktptr->data, and pkt_len
and buf_len directly from pktptr->len, rather than chaining one field
through the other. This avoids making the reader trace a dependency
between the two assignments to see that they end up with the same
value.

No functional change.

v2: Assign each field directly from its source value (pktptr->data /
    pktptr->len) instead of chaining one field's assignment through
    the other, per Greg's review comment that the v1 split was harder
    to read than the original.

This was already done in the 7.3-rc1 kernel release in commit
cb08dcd0a896 ("staging: rtl8723bs: Split multiple assignments in
_rtw_open_pktfile"), sorry.

thanks,
