From: Richard Neumann <[email protected]>
Cleaned up the i2c-amd-mp2-{pci,plat} drivers:
* Migrated kernel logging to pci_* log macros where applicable.
* Removed unused macros.
Richard Neumann (2):
Removed NIH log functions
Removed unused work_amd_i2c_common macro

First of all Subject should be in imperative mode with corresponding prefix,
something like: "i2c: amd-mp2: Remove NIH logging functions". Same to the rest
of the series.
While at it, drop useless __func__ parameters.

E.g. this will become one line after dropping __func__.
...
Also in some cases, like here, you may consider simple trick to reduce amount
of LOCs.
