Subject: [merged] drivers-platform-olpc-olpc-ecc-initialise-earlier.patch removed from -mm tree To: dsd@xxxxxxxxxx,dilinger@xxxxxxxxxx,pgf@xxxxxxxxxx,stable@xxxxxxxxxxxxxxx,tglx@xxxxxxxxxxxxx,mm-commits@xxxxxxxxxxxxxxx From: akpm@xxxxxxxxxxxxxxxxxxxx Date: Fri, 23 Aug 2013 12:06:13 -0700 The patch titled Subject: drivers/platform/olpc/olpc-ec.c: initialise earlier has been removed from the -mm tree. Its filename was drivers-platform-olpc-olpc-ecc-initialise-earlier.patch This patch was dropped because it was merged into mainline or a subsystem tree ------------------------------------------------------ From: Daniel Drake <dsd@xxxxxxxxxx> Subject: drivers/platform/olpc/olpc-ec.c: initialise earlier Being a low-level component, various drivers (e.g. olpc-battery) assume that it is ok to communicate with the OLPC Embedded Controller during probe. Therefore the OLPC EC driver must be initialised before other drivers try to use it. This was the case until it was recently moved out of arch/x86 and restructured around commits ac2504151f5af27b ("Platform: OLPC: turn EC driver into a platform_driver") and 85f90cf6ca569 ("x86: OLPC: switch over to using new EC driver on x86"). Use arch_initcall so that olpc-ec is readied earlier, matching the previous behaviour. Fixes a regression introduced in Linux-3.6 where various drivers such as olpc-battery and olpc-xo1-sci failed to load due to an inability to communicate with the EC. The user-visible effect was a lack of battery monitoring, missing ebook/lid switch input devices, etc. Signed-off-by: Daniel Drake <dsd@xxxxxxxxxx> Cc: Andres Salomon <dilinger@xxxxxxxxxx> Cc: Paul Fox <pgf@xxxxxxxxxx> Cc: Thomas Gleixner <tglx@xxxxxxxxxxxxx> Cc: <stable@xxxxxxxxxxxxxxx> Signed-off-by: Andrew Morton <akpm@xxxxxxxxxxxxxxxxxxxx> --- drivers/platform/olpc/olpc-ec.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff -puN drivers/platform/olpc/olpc-ec.c~drivers-platform-olpc-olpc-ecc-initialise-earlier drivers/platform/olpc/olpc-ec.c --- a/drivers/platform/olpc/olpc-ec.c~drivers-platform-olpc-olpc-ecc-initialise-earlier +++ a/drivers/platform/olpc/olpc-ec.c @@ -330,7 +330,7 @@ static int __init olpc_ec_init_module(vo return platform_driver_register(&olpc_ec_plat_driver); } -module_init(olpc_ec_init_module); +arch_initcall(olpc_ec_init_module); MODULE_AUTHOR("Andres Salomon <dilinger@xxxxxxxxxx>"); MODULE_LICENSE("GPL"); _ Patches currently in -mm which might be from dsd@xxxxxxxxxx are origin.patch -- To unsubscribe from this list: send the line "unsubscribe stable" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
