[PATCH 0/8] i2c: nomadik: fix several issues in fault handling, optimize layout

[Dmitry Guzman]

This patchset fixes several issues in i2c-nomadik driver.

Patches #1..#5 were previously submitted as a part of a patchset that
introduces detailed fault reporting feature in i2c-nomadik and
i2c-designware drivers and i2c-core.

In patch #5, the new structure declaration is moved to different place
to make it independent of patch #3 (avoid merge conflicts).

Patches #6..#8 fix other pre-existing issues found by AI review of that
patchset.

All patches are mutually independent and may be applied separately.

Patch #1 Optimize struct layout.
Patch #2 Remove automatic retransfer on failures.
Patch #3 Fix error codes returned by xfer() callback.
Patch #4 Avoid excessive prints by replacing dev_err() with dev_dbg() on
	I2C faults.
Patch #5 Add quirks that describe hardware limitations of the controller.
Patch #6 Handle PM runtime errors.
Patch #7 Fix race condition with IRQ handler.
Patch #8 Fix possible long busy-wait loop in interrupt handler.
