Hi All,
While working on suspend/resume support for Samsung Exynos5433-based TM2 board (arch/arm64/boot/dts/exynos/exynos5433-tm2.dts), I've noticed that v4.16 kernel release introduced some serious problems with regulator configuration in system suspend state. Further investigation revealed that the following 2 commits are responsible for my issues:
1. f7efad10b5c4: regulator: add PM suspend and resume hooks 2. 72069f9957a1: regulator: leave one item to record whether regulator is enabled
I've been really surprised that no-one noticed those issues for almost 4 kernel releases. Please review my fixes and apply to v4.19-rcX if possible.
Best regards Marek Szyprowski, PhD Samsung R&D Institute Poland
Patch summary:
Marek Szyprowski (2): regulator: Fix useless O^2 complexity in suspend/resume regulator: Fix 'do-nothing' value for regulators without suspend state
