Subject: [PATCH v5 0/4] hwmon: (ina3221) Implement PM runtime to save power

This series patches implement PM runtime feature in the ina3221 hwmon
driver (PATCH-4). However, PATCH-[1:3] are required to make sure that
the PM runtime feature would be functional and safe.

 * Used i2c_client dev pointer for pm runtime callbacks (PATCH-4)
v3->v4:
 * Added generic pm runtime functions to hwmon class (PATCH-1)
 * Updated to pass pm pointer via _with_info API (PATCH-5)
v2->v3:
 * Dropped timeout dev_err messages as it's indicated in errno (PATCH-4)
 * Improved a dev_err message and comments (PATCH-5)
v1->v2:
 * Added device pointer check (PATCH-1)
 * Returned 0 for alert flags (PATCH-2)
 * Moved CVRF polling to data read routine (PATCH-4)
 * Bypassed i2c_client->dev in suspend/resume() (PATCH-5)
