staging: board: Fix uninitialized spinlock when attaching genpd

On Armadillo-800-EVA with CONFIG_DEBUG_SPINLOCK=y: BUG: spinlock bad magic on CPU#0, swapper/1 lock: lcdc0_device+0x10c/0x308, .magic: 00000000, .owner: /-1, .owner_cpu: 0 CPU: 0 PID: 1 Comm: swapper Not tainted 5.11.0-rc5-armadillo-00036-gbbca04be7a80-dirty #287 Hardware name: Generic R8A7740 (Flattened Device Tree) [] (unwind_backtrace) from [] (show_stack+0x10/0x14) [] (show_stack) from [] (do_raw_spin_lock+0x20/0x94) [] (do_raw_spin_lock) from [] (dev_pm_get_subsys_data+0x8c/0x11c) [] (dev_pm_get_subsys_data) from [] (genpd_add_device+0x78/0x2b8) [] (genpd_add_device) from [] (of_genpd_add_device+0x34/0x4c) [] (of_genpd_add_device) from [] (board_staging_register_device+0x11c/0x148) [] (board_staging_register_device) from [] (board_staging_register_devices+0x24/0x28) of_genpd_add_device() is called before platform_device_register(), as it needs to attach the genpd before the device is probed. But the spinlock is only initialized when the device is registered. Fix this by open-coding the spinlock initialization, cfr. device_pm_init_common() in the internal drivers/base code, and in the SuperH early platform code.

clkdev: remove CONFIG_CLKDEV_LOOKUP

2021-06-08T15:00:09+00:00

This option is now synonymous with CONFIG_HAVE_CLK, so use the latter globally. Any out-of-tree platform ports that still use a private clk_get()/clk_put() implementation should move to CONFIG_COMMON_CLK. Signed-off-by: Arnd Bergmann

staging: add missing SPDX lines to Makefile files

2019-04-03T09:10:15+00:00

There are a few remaining drivers/staging/*/Makefile files that do not have SPDX identifiers in them. Add the correct GPL-2.0 identifier to them to make scanning tools happy. Reviewed-by: Mukesh Ojha Signed-off-by: Greg Kroah-Hartman
