Subject: [PATCH 0/5] mfd: qcom-spmi-pmic: fix revid implementation

The Qualcomm SPMI PMIC revid implementation is broken in multiple ways
that can lead to resource leaks and crashes. This series reworks the
implementation so that can be used safely.

Included is also a rename of the SPMI device lookup helper which can
hopefully help prevent similar leaks from being reintroduced.
