Re: [PATCH] staging: pi433: fix missing break in switch statement.

Hi all!

Tryed to cross check...

Don't get it, sorry.

On my private version control (my SVN), where I initially developed the driver the break isn't missing.
Same with my git copy of Gregs staging tree. Break is there...

Who removed it, why is it missing in Colins copy?

Am I working on a wrong version?

Can anybody help me?

Thanks,

Marcus

The PI433_IOC_WR_RX_CFG case is missing a break and will fall through
to the default case and errorenously return -EINVAL. Fix this by
adding in missing break.
