[PATCH v1 11/27] ACPICA: fix I2C LVR item count in the conversion table
From: Rafael J. Wysocki
Date: Wed May 27 2026 - 14:22:40 EST
From: Akhil R <akhilrajeev@xxxxxxxxxx>
For ACPI_RSC_MOVE8, the 'Value' field in struct acpi_rsconvert_info
is the item count count and not a bit position like for the
bitflags. Set 'Value' as '1' to fix this.
Conversion still works coincidentally with '0' because
item_count is not reset between table entries, and the previous
count value was taking effect.
