Subject: [PATCH v6 0/2] i2c: designware-platdrv: simplify reset control and fix cleanup on probe failure

This series simplifies error handling and reset control management in
the DesignWare I2C platform driver.

Patch 1 replaces the manual reset control acquisition and deassertion
with the devm_reset_control_get_optional_exclusive_deasserted()
function. This simplifies the code by eliminating explicit deassertion
calls and associated error handling while maintaining the same
functionality through automatic resource management.

Patch 2 removes the unnecessary goto label for cleanup on probe failure.
The cleanup operations are straightforward and can be handled directly
in the error path, making the control flow more readable without
changing the error handling semantics.

Thank you!
