2025-07-10mfd: exynos-lpass: Fix another error handling path in exynos_lpass_probe()Christophe JAILLET
[ Upstream commit f41cc37f4bc0e8cd424697bf6e26586cadcf4b9b ] If devm_of_platform_populate() fails, some clean-up needs to be done, as already done in the remove function. Add a new devm_add_action_or_reset() to fix the leak in the probe and remove the need of a remove function.

2025-05-29mfd: tps65219: Remove TPS65219_REG_TI_DEV_ID checkShree Ramamoorthy
[ Upstream commit 76b58d5111fdcffce615beb71520bc7a6f1742c9 ] The chipid macro/variable and regmap_read function call is not needed because the TPS65219_REG_TI_DEV_ID register value is not a consistent value across TPS65219 PMIC config versions. Reading from the DEV_ID register without a consistent value to compare it to isn't useful. There isn't a way to verify the match data ID is the same ID read from the DEV_ID device register. 0xF0 isn't a DEV_ID value consistent across TPS65219 NVM configurations. For TPS65215, there is a consistent value in bits 5-0 of the DEV_ID register. However, there are other error checks in place within probe() that apply to both PMICs rather than keeping this isolated check for one PMIC.

2025-02-08mfd: syscon: Fix race in device_node_get_regmap()Rob Herring (Arm)
[ Upstream commit 805f7aaf7fee14a57b56af01d270edf6c10765e8 ] It is possible for multiple, simultaneous callers calling device_node_get_regmap() with the same node to fail to find an entry in the syscon_list. There is a period of time while the first caller is calling of_syscon_register() that subsequent callers also fail to find an entry in the syscon_list and then call of_syscon_register() a second time. Fix this by keeping the lock held until after of_syscon_register() completes and adds the node to syscon_list. Convert the spinlock to a mutex as many of the functions called in of_syscon_register() such as kzalloc() and of_clk_get() may sleep.

The description became out-of-date after a bunch of changes e.g: - commit 5668bfdd90cd ("platform/chrome: cros_ec_dev - Register cros-ec sensors"). - commit ea01a31b9058 ("cros_ec: Split cros_ec_devs module"). - commit 5e0115581bbc ("cros_ec: Move cros_ec_dev module to drivers/mfd"). Update the description. Signed-off-by: Tzung-Bi Shih <tzungbi@kernel.org> Link: https://lore.kernel.org/r/20240822121539.4265-1-tzungbi@kernel.org Signed-off-by: Lee Jones <lee@kernel.org>

2024-09-11platform/x86: intel_scu_ipc: Move intel_scu_ipc.h out of arch/x86/include/asmMika Westerberg
This is a platform/x86 library that is mostly being used by other drivers not directly under arch/x86 anyway (with the exception of the Intel MID setup code) so it makes sense that it lives under the platform_data/x86/ directory instead. No functional changes intended.
