GCC is upset that we check the return value of plfxlc_usb_dev() even tho it can't be NULL: drivers/net/wireless/purelifi/plfxlc/usb.c: In function ‘resume’: drivers/net/wireless/purelifi/plfxlc/usb.c:840:20: warning: the comparison will always evaluate as ‘true’ for the address of ‘dev’ will never be NULL [-Waddress] 840 | if (!pl || !plfxlc_usb_dev(pl)) | ^ plfxlc_usb_dev() returns an address of one of the members of pl, so it's safe to drop these checks.
