Subject: [PATCH AUTOSEL 4.19 638/671] regulator: ab8500: Remove SYSCLKREQ from enum ab8505_regulator_id

From: Stephan Gerhold <stephan@...hold.net>

[ Upstream commit 458ea3ad033fc86e291712ce50cbe60c3428cf30 ]

Those regulators are not actually supported by the AB8500 regulator
driver. There is no ab8500_regulator_info for them and no entry in
ab8505_regulator_match.

As such, they cannot be registered successfully, and looking them
up in ab8505_regulator_match causes an out-of-bounds array read.

Fixes: 547f384f33db ("regulator: ab8500: add support for ab8505")
