From 2b6c0e152868c9c5939a5c5094d5b2be61cf48e6 Mon Sep 17 00:00:00 2001 From: Linus Walleij Date: Fri, 28 Oct 2022 11:23:32 +0200 Subject: bcma: Use the proper gpio include The is including the legacy header to obtain struct gpio_chip. Instead, include where this struct is defined. It turns out that the brcm80211 brcmsmac depends on this to bring in the symbol gpio_is_valid(). 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. The whole check can be dropped because the bcma_gpio is initialized in the declarations: struct gpio_chip *bcma_gpio = &cc_drv->gpio; And this can never be NULL.

Actually use the union and perform explicit member selection in the function body instead of having a function prototype mismatch. There are no resulting binary differences before/after changes.
