The conversion looks correct, and I see that you have
driverdev-devel@xxxxxxxxxxxxxxxxxxxxxx with this series now (as I just
replied to the rtl8192e series, you missed that there). You should
still add linux-kernel@xxxxxxxxxxxxxxx for completeness when you
resend (don't resend just for the Cc).

This is nonstandard coding style. I realize you are trying to fit in with what
the driver does for other functions, but since this is a staging driver, it's
better to convert it to normal kernel style when you make a change like this.

so just call wait_for_completion_interruptible() here directly and remove the
extra braces and the comparison of the return value.
