[PATCH v2 1/3] net: Discard pm_runtime_put() return value

[Rafael J. Wysocki]

Hi All,

This mostly is a resend of patches [10-12/23] from:

https://lore.kernel.org/linux-pm/6245770.lOV4Wx5bFT@rafael.j.wysocki/

as requested by Jakub, except for the last patch that has been fixed
while at it and so the version has been bumped up.

The patches are independent of each other and they are all requisite
for converting pm_runtime_put() into a void function.

Thanks!
