Subject: [PATCH v2] arm: exynos_config: Restore debugfs support
Date: Fri,  6 Dec 2019 13:47:21 +0100	[thread overview]
Message-ID: <20191206124721.9025-1-m.szyprowski@samsung.com> (raw)
In-Reply-To: CGME20191206124826eucas1p246538607df51f2d68bce3b09d974b292@eucas1p2.samsung.com

Commit 9f532d26c75c ("ARM: exynos_defconfig: Trim and reorganize with
savedefconfig") removed explicit enable line for CONFIG_DEBUG_FS, because
that feature has been selected by other enabled options: CONFIG_TRACING,
which in turn had been selected by CONFIG_PERF_EVENTS and
CONFIG_PROVE_LOCKING.

In meantime, commit 0e4a459f56c3 ("tracing: Remove unnecessary DEBUG_FS
dependency") removed the dependency between CONFIG_DEBUG_FS and
CONFIG_TRACING, so CONFIG_DEBUG_FS is no longer enabled in default builds.

Enable it again explicitly, as debugfs support is essential for various
automated testing tools.
