(adding Linus Walleij and Alexander Stein to Cc) Unfortunately, the changelog also doesn't say what triggered that change. I guess there was a driver that did 'select OF_GPIO' and had a dependency on COMPILE_TEST, though I don't see any driver doing that in linux-next. I think the commit should just be reverted, it clearly breaks stuff, and whatever needs it can be fixed in a better way. Specifically, we have three ways that the OF_GPIO symbol is used: a) it is implicitly enabled when both GPIOLIB and OF are turned on b) some drivers 'depends on OF_GPIO' c) some other drivers 'select OF_GPIO' The combination of b) and c) can easily lead to circular dependencies, and is also confusing. It would be better to change all of those to 'depends on'.
