Subject: ACPI / blacklist: add _REV quirk for Dell Inspiron 7537
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=2cff319e9666f534a7538aa1f4178d1f799b068a;p=linux.git

ACPI / blacklist: add _REV quirk for Dell Inspiron 7537

The battery can only be detected after AC power adapter event.

Adding the machine to acpi_rev_dmi_table[] can work around this
issue.
