[PATCH v2] mtd: nand: nandsim: fix error check

debugfs_create_dir() and debugfs_create_file() returns NULL on error or a pointer on success. They do not return the error value with ERR_PTR. So we should not check the return with IS_ERR_OR_NULL, instead we should just check for NULL. Signed-off-by: Sudip Mukherjee --- v2: nuked err drivers/

[PATCH -tip v3 0/9] ftrace: selftests: Add full glob matching and update ftracetest

Hi, Here is the 3rd version of the series of patches to add full glob matching support in ftrace, and update ftracetest to fix bugs and add test for the glob matching and hexadecimal types. Previous version is here: https://lkml.org/lkml/2016/10/30/16 I've fix some bugs related to ftrace kconfi

[PATCH -tip v3 1/9] ftrace: Support full glob matching

Use glob_match() to support flexible glob wildcards (*,?) and character classes ([) for ftrace. Since the full glob matching is slower than the current partial matching routines(*pat, pat*, *pat*), this leaves those routines and just add MATCH_GLOB for complex glob expression. e.g. [root@loca

[PATCH -tip v3 2/9] selftests: ftrace: Initialize ftrace before each test

Reset ftrace to initial state before running each test. This fixes some test cases to enable tracing before starting trace test. This can avoid false-positive failure when previous testcase fails while disabling tracing. Signed-off-by: Masami Hiramatsu Suggested-by: Steven Rostedt --- Changes

[PATCH -tip v3 3/9] selftests: ftrace: Add --quiet option not to show error logs on screen

Since the verbose error logs scrolls out previous test results --quiet option suppress to show such message. e.g. # ./ftracetest -q === Ftrace unit tests === [1] Basic trace file check [PASS] [2] Basic test for tracers [PASS] [3] Basic trace clock test [PASS] [4] Basic event tracin

[PATCH -tip v3 5/9] selftests: ftrace: Fix trigger-mod to run without syscall trace

Since histogram trigger id.syscall depends on CONFIG_FTRACE_SYSCALLS, a testcase in trigger-modifier test fails if that config is disabled. Fix this bug by using flexible pattern to check the histogram output. Signed-off-by: Masami Hiramatsu --- .../ftrace/test.d/trigger/trigger-hist-mod.tc

[PATCH -tip v3 8/9] selftests: ftrace: Add a testcase for function filter glob match

Add function filter glob matching test case. This checks whether the kernel supports glob matching (front match, end match, middle match, side match, character class and '?'). Here is the test result. - ./ftracetest test.d/ftrace/func-filter-glob.tc === Ftrace unit tests === [1] ftrace

[PATCH -tip v3 4/9] selftests: ftrace: Check whether snapshot trigger is supported correctly

[PATCH] drm/sun4i: Only count TCON endpoints as valid outputs

The sun4i DRM driver counts the number of endpoints it found and registers the whole DRM pipeline if any endpoints are found. However, if the TCON and its child endpoints (LCD panels, TV encoder, HDMI encoder, MIPI DSI encoder, etc.) aren't found, that means we don't have any usable CRTCs, and the

While the VSC8601 can set more fine-grained delays, the standard skew settings work out of the box. The same heuristic is used to determine when this skew should be enabled as in vsc824x_conf
