[PATCH 4.19 098/146] tools: gpio: Fix out-of-tree build regression

[Greg Kroah-Hartman]

From: Anssi Hannula <anssi.hannula@xxxxxxxxxx>

commit 82f04bfe2aff428b063eefd234679b2d693228ed upstream.

Commit 0161a94e2d1c7 ("tools: gpio: Correctly add make dependencies for
gpio_utils") added a make rule for gpio-utils-in.o but used $(output)
instead of the correct $(OUTPUT) for the output directory, breaking
out-of-tree build (O=xx) with the following error:

  No rule to make target 'out/tools/gpio/gpio-utils-in.o', needed by 'out/tools/gpio/lsgpio-in.o'.  Stop.

Fix that.

Fixes: 0161a94e2d1c ("tools: gpio: Correctly add make dependencies for gpio_utils")
