I am sending a combined patch with this and the other bcma patch because they happen to depend on each other. Dunno how to tag a patch that affects bcma and brcn80211 at the same time so you will probably have to edit it anyway. Yours, Linus Walleij

The driver looks up the BCMA parent GPIO driver and checks that this succeeds, but then it goes on to use the deprecated GPIO call gpio_is_valid() to check the consistency of the .base member of the BCMA GPIO struct. Surely this belongs in the BCMA driver: we cannot have all drivers performing cosistency checks on the internals of things they are passed.
