ab8500_btemp: Demote initcall sequence

2013-03-03T22:03:38Z

commit eeb0751c99522a4d1bbcc7b6bc1460cd07d07488 upstream. Power supply subsystem creates thermal zone device for the property 'POWER_SUPPLY_PROP_TEMP' which requires thermal subsystem to be ready before 'ab8500 battery temperature monitor' driver is initialized. ab8500 btemp driver is initialized with subsys_initcall whereas thermal subsystem is initialized with fs_initcall which causes thermal_zone_device_register(...) to crash since the required structure 'thermal_class' is not initialized yet: Unable to handle kernel NULL pointer dereference at virtual address 000000a4 pgd = c0004000 [000000a4] *pgd=00000000 Internal error: Oops: 5 [#1] PREEMPT SMP ARM Modules linked in: CPU: 0 Tainted: G W (3.8.0-rc4-00001-g632fda8-dirty #1) PC is at _raw_spin_lock+0x18/0x54 LR is at get_device_parent+0x50/0x1b8 pc : [] lr : [] psr: 60000013 sp : ef04bdc8 ip : 00000000 fp : c0446180 r10: ef216e38 r9 : c03af5d0 r8 : ef275c18 r7 : 00000000 r6 : c0476c14 r5 : ef275c18 r4 : ef095840 r3 : ef04a000 r2 : 00000001 r1 : 00000000 r0 : 000000a4 Flags: nZCv IRQs on FIQs on Mode SVC_32 ISA ARM Segment kernel Control: 10c5787d Table: 0000404a DAC: 00000015 Process swapper/0 (pid: 1, stack limit = 0xef04a238) Stack: (0xef04bdc8 to 0xef04c000) [...] [] (_raw_spin_lock+0x18/0x54) from [] (get_device_parent+0x50/0x1b8) [] (get_device_parent+0x50/0x1b8) from [] (device_add+0xa4/0x574) [] (device_add+0xa4/0x574) from [] (thermal_zone_device_register+0x118/0x938) [] (thermal_zone_device_register+0x118/0x938) from [] (power_supply_register+0x170/0x1f8) [] (power_supply_register+0x170/0x1f8) from [] (ab8500_btemp_probe+0x208/0x47c) [] (ab8500_btemp_probe+0x208/0x47c) from [] (platform_drv_probe+0x14/0x18) [] (platform_drv_probe+0x14/0x18) from [] (driver_probe_device+0x74/0x20c) [] (driver_probe_device+0x74/0x20c) from [] (__driver_attach+0x8c/0x90) [] (__driver_attach+0x8c/0x90) from [] (bus_for_each_dev+0x4c/0x80) [] (bus_for_each_dev+0x4c/0x80) from [] (bus_add_driver+0x16c/0x23c) [] (bus_add_driver+0x16c/0x23c) from [] (driver_register+0x78/0x14c) [] (driver_register+0x78/0x14c) from [] (do_one_initcall+0xfc/0x164) [] (do_one_initcall+0xfc/0x164) from [] (kernel_init+0x120/0x2b8) [] (kernel_init+0x120/0x2b8) from [] (ret_from_fork+0x14/0x3c) Code: e3c3303f e5932004 e2822001 e5832004 (e1903f9f) ---[ end trace ed9df72941b5bada ]--- Signed-off-by: Rajanikanth H.V Signed-off-by: Anton Vorontsov Signed-off-by: Greg Kroah-Hartman

Drivers: power: remove __dev* attributes.

2013-01-03T23:57:14Z

CONFIG_HOTPLUG is going away as an option. As a result, the __dev* markings need to be removed. This change removes the use of __devinit, __devexit_p, __devinitconst, and __devexit from these drivers. Based on patches originally written by Bill Pemberton, but redone by me in order to handle some of the coding style issues better, by hand.

Pull late ARM cleanups for omap from Olof Johansson: "From Tony Lindgren: Here are few more patches to finish the omap changes for multiplatform conversion that are not strictly fixes, but were too complex to do with the dependencies during the merge window. Those are to move of serial-omap.h to platform_data, and the removal of remaining cpu_is_omap macro usage outside mach-omap2.

ARM: OMAP2+: Drop plat/cpu.h for omap2plus

2012-12-17T18:50:41Z

The cpu_is_omap macros are now local to arch/arm/mach-omap2 in soc.h and plat/cpu.h can finally be dropped for omap2+. Thanks everybody for help with fixing the drivers. Note that we can now also remove the unused plat/cpu.h from smartreflex.c and isp.c as they will cause compile errors with ARCH_MULTIPLATFORM enabled.

charger-manager: Fix bug when check dropped voltage after fullbatt event

2012-12-17T06:45:58Z

This patch check difference value between current voltage of battery and desc->fullbatt_uV whether positve or negative number. If difference value is negative number when current voltage of battery is larger than desc->fullbatt_uV, charger-manager return immediately because battery is fully charged.
