[PATCH v2] ACPI: Fixes device power states array overflow

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Commit 28c2103 added new state ACPI_STATE_D3_COLD, so the device power
states array must be expanded by one also.

v2: Use ACPI_D_STATE_COUNT instead of number 5 for the array size.
