4.4-stable review patch. If anyone has any objections, please let me know.
------------------ From: Arnd Bergmann <[email protected]> commit a7b956fd38dd217dd78e3058110929f5ac914df1 upstream. The newly introduced as3722_i2c_suspend/resume functions are built unconditionally, but only used when power management is enabled, so we get a warning otherwise: drivers/mfd/as3722.c:427:12: warning: 'as3722_i2c_suspend' defined but not used [-Wunused-function] drivers/mfd/as3722.c:438:12: warning: 'as3722_i2c_resume' defined but not used [-Wunused-function] This marks them both as __maybe_unused, which avoids an ugly #ifdef and gives us best compile-time coverage. When they are unused, the compiler will silently drop the functions from its output.
