selftests/ftrace: Fix unique symbol check in kprobe_non_uniq_symbol.tcgrafted

The current regex also matches symbols in modules, which makes the
test fail on s390 where name_show is present only once in the kernel,
but also multiple times in modules:

000001b1401cdc20 t name_show
000001b0c05e6c40 t name_show    [mdev]
000001b0c0495f30 t name_show    [i2c_core]

Fix this by changing the regular expression to only match the function
name.

+Display Hardware Handling
+=========================
+
+This section covers everything related to the display hardware including
+the mode setting infrastructure, plane, sprite and cursor handling and
+display, output probing and related topics.

+KUnit Tests
+===========
+
+The VC4 Driver uses KUnit to perform driver-specific unit and
+integration tests.
+
+These tests are using a mock driver and can be ran using the
+command below, on either arm or arm64 architectures,
+
+.. code-block:: bash
+
+	$ ./tools/testing/kunit/kunit.py run \
+		--kunitconfig=drivers/gpu/drm/vc4/tests/.kunitconfig \
+		--cross_compile aarch64-linux-gnu- --arch arm64
+
+Parts of the driver that are currently covered by tests are:
+ * The HVS to PixelValve dynamic FIFO assignment, for the BCM2835-7
+   and BCM2711.
