Subject: [PATCH 0/2] net: wwan: t7xx: Fix Runtime PM implementation

d10b3a695ba0 ("net: wwan: t7xx: Runtime PM") introduced support for
Runtime PM for this driver, but due to a bug in the initialization logic
the usage refcount would never reach 0, leaving the feature unused.
This patchset addresses that, together with a bug found after runtime
suspend was enabled.
