From: David Brownell Date: Thu, 16 Oct 2008 05:02:46 +0000 (-0700) Subject: spi: core and gpio expanders use subsys_init X-Git-Tag: v2.6.28-rc1~451 X-Git-Url: https://git.openpandora.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=673c0c00382ed807f09d94e806f3519ddeeb4f70;p=pandora-kernel.git spi: core and gpio expanders use subsys_init Make the SPI external GPIO expander drivers register themselves at subsys_initcall() time when they're statically linked, and make the SPI core do its driver model initialization earlier so that's safe. SOC-integrated GPIOs are available starting very early -- often before initcalls start to run, or earily in arch_initcall() at latest -- so this improves consistency, letting more subsystems rely on GPIOs being usable by their own subsys_initcall() code.
