[PATCH v1 2/4] wifi: rsi: sdio: Reduce use of #ifdef for CONFIG_PM
Posted by Uwe Kleine-König 1 month, 3 weeks ago
This drops two #ifdefs (which is good because they are ugly) without
changing semantics. This also improves compile coverage because all the
code in the first #ifdef block is now compiled even for configurations
without CONFIG_PM (and then thrown away).

This didn't build, and given that we never got 1/4 I'm going to assume
it wasn't destined to the wireless tree.

Yes, this depends on patch #1, I expected the series to go in via
whatever tree sdio usually goes in and didn't notice that all users are
in the wireless subsystem.

The kernel robot also found an issue[1] that needs addressing (probably
by dropping patch #2 from the series). Will look into that next year.

Best regards
Uwe
