I found a use_count leakage towards supply regulator of rdev with boot-on option. ┌───────────────────┐ ┌───────────────────┐ │ regulator_dev A │ │ regulator_dev B │ │ (boot-on) │ │ (boot-on) │ │ use_count=0 │
◀ ──supply──│ use_count=1 │ │ │ │ │ └───────────────────┘ └───────────────────┘ In case of rdev(A) configured with `regulator-boot-on', the use_count of supplying regulator(B) will increment inside regulator_enable(rdev->supply). Thus, B will acts like always-on, and further balanced regulator_enable/disable cannot actually disable it anymore. However, B was also configured with `regulator-boot-on', we wish it could be disabled afterwards.

Print error message for potential EPROBE_DEFER error using dev_err_probe, which captures the reason in /sys/kernel/debug/devices_deferred and otherwise silences the message. Signed-off-by:

Reduce usage of 'struct rk808' (driver data of the parent MFD), so that only the chip variant field is still being accessed directly. This allows restructuring the MFD driver to support SPI based PMICs. Acked-by:

Since commit 0166dc11 ("of: make CONFIG_OF user selectable"), it is possible to test-build any driver which depends on OF on any architecture by explicitly selecting OF. Therefore depending on COMPILE_TEST as an alternative is no longer needed. It is actually better to always build such drivers with OF enabled, so that the test builds are closer to how each driver will actually be built on its intended target. Building them without OF may not test much as the compiler will optimize out potentially large parts of the code. In the worst case, this could even pop false positive warnings. Dropping COMPILE_TEST here improves the quality of our testing and avoids wasting time on non-existent issues. As a minor optimization, this also lets us drop several occurrences of of_match_ptr(), __maybe_unused and some ifdef guarding, as we now know what all of this will resolve to, we might as well save cpp some work.

Merge series from Matti Vaittinen <mazziesaccount@gmail.com>: Minor (printing) improvements for ROHM regulator drivers. This series: - Drops an unnecessary info print from bd718x7. (Added a fixes tag for this but not really sure if worth adding to stable) - Convert the ROHM BDxxxxx PMIC regulator drivers to use dev_err_probe(). - Change the probe logic for bd718x7 to favor the more usual devm-style where errors are returned immediately.

The dev_err_probe() has (at least) following benefits over dev_err() when printing an error print for a failed function call at a device driver probe: - Omit error level print if error is 'EPRBE_DEFER' - Standardized print format for returned error - return the error value allowing shortening calls like: if (ret) { dev_err(...); return ret; } to if (ret) return dev_err_probe(...); Convert the ROHM BD718x7 regulator driver to use the dev_err_probe() when returned error is not hard-coded constant. NOTE: This commit also changes the error handling path to return immediately from a spot where the error is spotted instead of using a single point of exit.

When Madera support was added to this driver the code was left using ARIZONA_* defines. This wasn't causing any problem because those defines just happened to have the same value as the equivalent MADERA_* defines. But it is not ideal to assume this, and future devices that can share this driver do not have the same register map. Fix the code to refer to the register data in struct regulator_desc.
