The patch titled gpio: i2c expanders use subsys_init has been removed from the -mm tree. Its filename was gpio-i2c-expanders-use-subsys_init.patch This patch was dropped because it was merged into mainline or a subsystem tree The current -mm tree may be found at http://userweb.kernel.org/~akpm/mmotm/ ------------------------------------------------------ Subject: gpio: i2c expanders use subsys_init From: David Brownell <dbrownell@xxxxxxxxxxxxxxxxxxxxx> Make the I2C external GPIO expander drivers register themselves at subsys_initcall() time when they're statically linked. SOC-integrated GPIOs are available starting very early -- early in arch_initcall() at latest, but often even before initcalls start to run -- so this improves consistency, so more subsystems can rely on GPIOs in their own subsys_initcall() code. (This isn't a theoretical problem. This is one of several patches needed to resolve oopsing observed when statically linking kernels on a DaVinci EVM. Its pcf857x GPIOs needed to be available well before some other drivers initialized.)
