X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=d8a26a18d971cd52a9b253aa2cff7dcb20187711;p=linux.git

gpiolib: acpi: Check for errors first in acpi_find_gpio()

It's better to parse the code when the usual pattern is being used,
i.e. checking for error condition first.

There is no functional or code generation change (tested in LLVM).
