mfd: da9061: Fix Failed to set Two-Wire Bus Mode.

2022-10-21T10:38:52+00:00

[ Upstream commit 834382ea32865a4bdeae83ec2dcb9321dc9489f2 ]

In da9062_i2c_probe() regmap_clear_bits() tries to access CONFIG_J
register. As CONFIG_J is not present in da9061_aa_writeable_ranges[] probe
of da9061 fails:

  da9062 2-0058: Entering I2C mode!
  da9062 2-0058: Failed to set Two-Wire Bus Mode.
  da9062: probe of 2-0058 failed with error -5

Add CONFIG_J register to da9061_aa_writeable_ranges[].

mfd: sm501: Add check for platform_driver_register()

2022-10-21T10:38:52+00:00

[ Upstream commit 8325a6c24ad78b8c1acc3c42b098ee24105d68e5 ]

As platform_driver_register() can return error numbers,
it should be better to check platform_driver_register()
and deal with the exception.

mfd: fsl-imx25: Fix check for platform_get_irq() errors

2022-10-21T10:38:52+00:00

[ Upstream commit 75db7907355ca5e2ff606e9dd3e86b6c3a455fe2 ]

The mx25_tsadc_remove() function assumes all non-zero returns are success
but the platform_get_irq() function returns negative on error and
positive non-zero values on success.  It never returns zero, but if it
did then treat that as a success.

mfd: lp8788: Fix an error handling path in lp8788_irq_init() and lp8788_irq_init()

2022-10-21T10:38:51+00:00

[ Upstream commit 557244f6284f30613f2d61f14b579303165876c3 ]

In lp8788_irq_init(), if an error occurs after a successful
irq_domain_add_linear() call, it must be undone by a corresponding
irq_domain_remove() call.

irq_domain_remove() should also be called in lp8788_irq_exit() for the same
reason.

mfd: lp8788: Fix an error handling path in lp8788_probe()

[ Upstream commit becfdcd75126b20b8ec10066c5e85b34f8994ad5 ]

Should an error occurs in mfd_add_devices(), some resources need to be
released, as already done in the .remove() function.

Add an error handling path and a lp8788_irq_exit() call to undo a previous
lp8788_irq_init().

If devm_of_platform_populate() fails, some resources need to be
released.

Introduce a mx25_tsadc_unset_irq() function that undoes
mx25_tsadc_setup_irq() and call it both from the new error handling path
of the probe and in the remove function.

 "Here are the updates for this merge window from the GPIO subsystem.

  We have more lines removed than added thanks to dropping of a driver
  for a platform that's no longer supported. Otherwise the changes are
  pretty straightforward: support for some new models, various
  improvements to existing drivers, some tweaks to the core library code
  and DT bindings updates.

  Summary:

   - remove gpio-vr41xx driver as the only platform using it got dropped
     too

   - add support for suspend/resume to gpio-davinci

   - improvements to the GPIO character device code

   - add support for disabling bias for in-kernel users (up until now
     only user-space could set it)

   - drop unused devm_gpio_free()

   - fix a refcount issue in gpiolib OF

   - use device match helpers where applicable

   - add support for a new model to gpio-rockchip

   - non-functional improvements in gpio-adp5588

   - improve and simplify teardown in gpio-twl4030 and gpio-ucb1400

   - modernize the gpio-74xx-mmio and gpio-adnp drivers

   - coding style improvements in gpio-xilinx, gpio-104-idi-48

   - support new model (pca9571) in gpio-pca9570

   - convert the DT bindings to YAML for gpio-mvebu and update the
     document

   - don't return error codes from remove() in gpio-brcmstb

   - add a library for the intel 8255 PPI interface and use it in
     drivers

   - reduce using magic numbers and improve code readability in several
     drivers

   - convert DT bindings to YAML for gpio-tpic2810

   - add new models to DT bindings for gpio-frl-imx

   - Kconfig improvements

   - other minor tweaks and improvements"
