The preferred style is this:

Fix the following sparse warnings:

drivers/net/wireless/purelifi/plfxlc/chip.c:36:31: sparse: expected unsigned short [usertype] beacon_interval
drivers/net/wireless/purelifi/plfxlc/chip.c:36:31: sparse: got restricted __le16 [usertype]

The subject should be:

[PATCH] plfxlc: fix le16_to_cpu warning for beacon_interval

I think there's no need to use three lines anymore, two lines should be
enough:

       if (!interval ||
           (chip->beacon_set && chip->beacon_interval == interval))
