Subject: Staging: quickstart: acpi_status is unsigned
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=f0903863099668d6b03c7ea90b2e58a7ad1be6a3;p=openwrt%2Fstaging%2Fblogic.git

Staging: quickstart: acpi_status is unsigned

acpi_bus_register_driver() returns an int, not acpi_status.  It returns
zero on success and negative error codes on failure, but acpi_status is
unsigned.  We can just use "ret" here.
