mfd: mt6360: Add bounds checking in Regmap read/write call-backs

2023-01-04T10:29:01Z

commit 5f4f94e9f26cca6514474b307b59348b8485e711 upstream. Fix the potential risk of OOB read if bank index is over the maximum. Refer to the discussion list for the experiment result on mt6370. https://lore.kernel.org/all/20220914013345.GA5802@cyhuang-hp-elitebook-840-g3.rt/ If not to check the bound, there is the same issue on mt6360.

mfd: qcom_rpm: Use devm_of_platform_populate() to simplify code

2022-12-31T12:33:12Z

[ Upstream commit e48dee96046246980d476714b3f6684d45f29c13 ] Use devm_of_platform_populate() instead of hand-writing it. This simplifies the code.

mfd: pm8008: Fix return value check in pm8008_probe()

2022-12-31T12:32:52Z

[ Upstream commit 14f8c55d48e02157519fbcb3a5de557abd8a06e2 ] In case of error, the function devm_regmap_init_i2c() returns ERR_PTR() and never returns NULL. The NULL test in the return value check should be replaced with IS_ERR().

mfd: qcom_rpm: Fix an error handling path in qcom_rpm_probe()

2022-12-31T12:32:52Z

[ Upstream commit 36579aca877a62f67ecd77eb3edefc4c86292406 ] If an error occurs after the clk_prepare_enable() call, a corresponding clk_disable_unprepare() should be called.

mfd: bd957x: Fix Kconfig dependency on REGMAP_IRQ

2022-12-31T12:32:52Z

[ Upstream commit 85842c46fd47fa6bd78681c154223bed27d5fd19 ] The BD957x driver uses REGMAP_IRQ but does not 'select' to depend on it. This can cause build failures. Select REGMAP_IRQ for BD957X.

mfd: axp20x: Do not sleep in the power off handler

2022-12-31T12:32:52Z

[ Upstream commit 3f37d4f695cff180033254b9ed5adc8ab927cba9 ] Since commit 856c288b0039 ("ARM: Use do_kernel_power_off()"), the function axp20x_power_off() now runs inside a RCU read-side critical section, so it is not allowed to call msleep().

Revert "mfd: syscon: Remove repetition of the regmap_get_val_endian()"

2022-10-23T19:04:56Z

This reverts commit 72a95859728a7866522e6633818bebc1c2519b17. It broke reboots on big-endian MIPS and MIPS64 malta QEMU instances, which use the syscon driver. Little-endian is not effected, which means likely it's important to handle regmap_get_val_endian() in this function after all.
