Subject: ACPI: blacklist win8 OSI for Dell Inspiron 7737
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=b753631b3576bf343151a82513c5d56fcda1e24f;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

ACPI: blacklist win8 OSI for Dell Inspiron 7737

With win8 capabiltiy, the machine will boot itself immediately after
shutdown command has executed.

Work around this issue by disabling win8 capcability.  This workaround
also makes wireless hotkey work.
