mfd: pm8008: Fix module autoloading

2023-07-23T11:49:37+00:00

commit d420c9886f5369697047b880221789bf0054e438 upstream.

Add the missing module device table alias to that the driver can be
autoloaded when built as a module.

mfd: stmpe: Only disable the regulators if they are enabled

2023-07-19T14:21:58+00:00

[ Upstream commit 104d32bd81f620bb9f67fbf7d1159c414e89f05f ]

In stmpe_probe(), if some regulator_enable() calls fail, probing continues
and there is only a dev_warn().

So, if stmpe_probe() is called the regulator may not be enabled. It is
cleaner to test it before calling regulator_disable() in the remove
function.

mfd: stmfx: Nullify stmfx->vdd in case of error

2023-07-19T14:21:57+00:00

[ Upstream commit 7c81582c0bccb4757186176f0ee12834597066ad ]

Nullify stmfx->vdd in case devm_regulator_get_optional() returns an error.
And simplify code by returning an error only if return code is not -ENODEV,
which means there is no vdd regulator and it is not an issue.

mfd: stmfx: Fix error path in stmfx_chip_init

[ Upstream commit f592cf624531286f8b52e40dcfc157a5a7fb115c ]

In error path, disable vdd regulator if it exists, but don't overload ret.
Because if regulator_disable() is successful, stmfx_chip_init will exit
successfully while chip init failed.

mfd: wcd934x: Fix an error handling path in wcd934x_slim_probe()

2023-07-19T14:21:56+00:00

[ Upstream commit f190b4891a3f9fac123a7afd378d4143a2723313 ]

If devm_gpiod_get_optional() fails, some resources need to be released, as
already done in the .remove() function.

While at it, remove the unneeded error code from a dev_err_probe() call.
It is already added in a human readable way by dev_err_probe() itself.

[ Upstream commit 43db1344e0f8c1eb687a1d6cd5b0de3009ab66cb ]

The fuel gauge in the RT5033 PMIC (rt5033-battery) has its own I2C bus
and interrupt lines. Therefore, it is not part of the MFD device
and needs to be specified separately in the device tree.

mfd: intel_soc_pmic_chtwc: Add Lenovo Yoga Book X90F to intel_cht_wc_models

2023-05-24T16:32:42+00:00

[ Upstream commit ded99b89d25fd73a1d7bd910378e0339fd9d4c4a ]

The Android Lenovo Yoga Book X90F / X90L uses the same charger / fuelgauge
setup as the already supported Windows Lenovo Yoga Book X91F/L, add
a DMI match for this to intel_cht_wc_models with driver_data
set to INTEL_CHT_WC_LENOVO_YOGABOOK1.

When the quirk for the X91F/L was initially added it was written to
also apply to the X90F/L but this does not work because the Android
version of the Yoga Book uses completely different DMI strings.
Also adjust the X91F/L quirk to reflect that it only applies to
the X91F/L models.
