[PATCH rtw-next v2 0/2] wifi: rtlwifi/rtw89: remove conditional returns with no effect

[Sang-Heon Jeon]

Hello,

This series removes conditional returns where both branches return
the same value, so the check has no effect. As suggested by Ping-Ke,
the wifi patch of the treewide v1 series [1] is split per driver and
posted separately.

Both patches are generated by the Coccinelle script, which you can
find in v1.

---
Changes from v1 [1]
- Split the wifi patch per driver
- Change base to rtw/rtw-next
- Filter only rtlwifi and rtw89 changes

[Sang-Heon Jeon]

Both branches of the check return the same value, so the check has
no effect. Remove it and return the value directly.

This is the result of running the Coccinelle script from
scripts/coccinelle/misc/cond_return_no_effect.cocci.

I'd update the subject to be more specific during it gets merged.

For the record, I'd make subject more specific:
