[PATCH 22/34] drm/komeda: don't warn for unused debugfs files

[Arnd Bergmann]

From: Arnd Bergmann <arnd@xxxxxxxx>

With debugfs disabled, the komeda_register debugfs file is unused:

drivers/gpu/drm/arm/display/komeda/komeda_dev.c:44:1: error: unused variable 'komeda_register_fops' [-Werror,-Wunused-const-variable]
DEFINE_SHOW_ATTRIBUTE(komeda_register);

The komeda_debugfs_init() function already has a call to debugfs_initialized()
that ends up eliminating the file as dead code, so just drop the #ifdef
to get rid of the warning.

Fixes: 576832681891 ("arm/komeda: Compile komeda_debugfs_init() only if CONFIG_DEBUG_FS is enabled")
Fixes: 7d3cfb70a604 ("drm/komeda: Add debugfs node "register" for register dump")
