[PATCH] drm/i915/display: Include debugfs.h in intel_display_debugfs_params.c

[PATCH] drm/i915/display: Include debugfs.h in intel_display_debugfs_params.c

[Paz Zcharya]

Commit 8015bee0bfec ("drm/i915/display: Add framework to add parameters
specific to display") added the file intel_display_debugfs_params.c,
which calls the functions "debugfs_create_{bool, ulong, str}" -- all of
which are defined in <linux/debugfs.h>. The missing inclusion of this
header file is breaking the ChromeOS build -- add an explicit include
to fix that.

Thanks for the patch, apparently in our configs some paths lead to
debugfs.h. Just goes on to show how interdependent the kernel headers
are.

Out of curiousity, what value do you have for CONFIG_DEBUG_FS kconfig?

Thank you so much for the super prompt reply!

In ChromeOS the value is CONFIG_DEBUG_FS=y.

FYI, looks like we've got some hiccup in CI, will merge after we get
results.

BR,
