2011-01-13leds: add output inversion option to backlight triggerJanusz Krzysztofik
Extend the LED backlight tirgger driver with an option that allows for inverting the trigger output polarity. With the invertion option provided, I (ab)use the backlight trigger for driving a LED that indicates LCD display blank condtition on my Amstrad Delta videophone. Since the machine has no dedicated power LED, it was not possible to distinguish if the display was blanked, or the machine was turned off, without touching it. The invert sysfs control is patterned after a similiar function of the GPIO trigger driver.

2011-01-13leds-lp5521: modify the way of setting led device nameArun Murthy
Currently the led device name is fetched from the device_type in I2C_BOARD_INFO which comes from the platform data. This name is in turn used to create an entry in sysfs. If there exists two or more lp5521 on a particular platform, the device_type in I2C_BOARD_INFO has to be the same, else lp5521 driver probe wont be called and if used so, results in run time warning "cannot create sysfs with same name" and hence a failure. The name that is used to create sysfs entry is to be passed by the struct led_platform_data. Hence adding an element of type const char * and change in lp5521 driver to use this name in creating the led device if present else use the name obtained by I2C_BOARD_INFO.

2011-01-13leds: lp5521: fix circular lockingSamu Onkalo
Driver contained possibility for circular locking. One lock is held by sysfs-core and another one by the driver itself. This happened when the driver created or removed sysfs entries dynamically. There is no real need to do those operations. Now all the sysfs entries are created at probe and removed at removal. Engine load sysfs entries are now visible all the time. However, access to the entries fails if the engine is disabled or running.

2011-01-13omap4: Fix ULPI PHY init for ES1.0 SDPTony Lindgren
Commit 6aa85a5ae610106d89e50c7e1f760c56d12f9bc4 (omap4: 4430sdp: enable the ehci port on 4430SDP) added code to enable EHCI support on 4430sdp board. Looks like the ULPI pin does not seem to be muxed properly on ES1.0 SDP and this causes the system to reboot when the ULPI PHY is enabled. Fix this by muxing the pin, this is the same setting for both ES1.0 and ES2.0. Also add checking for gpio_request.

2011-01-13ALSA: hda - Add fixup-call in init callbackTakashi Iwai
In some cases, the fix-up is required in the init callback to be called both at the first initialization and at the resume. The new action type ALC_FIXUP_ACT_INIT is used for this case. So far, only ALC275_FIXUP_SONY_HWEQ uses this. Signed-off-by: Takashi Iwai <tiwai@suse.de>

2011-01-13ASoC: tegra: s/IS_ERR_OR_NULL/IS_ERR/ for clk_get_sysStephen Warren
A recent discussion on linux-arm-kernel noted that the value returned by clk_get_sys is an opaque token, and not strictly a pointer; it is meaningful only to the clock API, clients should not dereference the value, and the clock API must accept any non-IS_ERR value it returned. Hence, only IS_ERR is appropriate to interpret the result, not IS_ERR_OR_NULL. I checked that clk_get_sys in both ASoC's for-next and Tegra's for-next do behave as described; NULL is not returned in the case of error.

2011-01-13ASoC: soc-cache: Add support for default readable()/volatile() functionsDimitris Papastamos
For common scenarios, device drivers can provide a table of all the registers that are at least either readable/writable/volatile. The idea is that if a register lookup fails, all of its read/write/vol members will be zero and will be treated as default. This also reduces the size of the register access array.

2011-01-13perf record: Add "nodelay" mode, disabled by defaultKirill Smelkov
Sometimes there is a need to use perf in "live-log" mode. The problem is, for seldom events, actual info output is largely delayed because perf-record reads sample data in whole pages. So for such scenarious, add flag for perf-record to go in "nodelay" mode. To track e.g. what's going on in icmp_rcv while ping is running Use it with something like this: (1) $ perf probe -L icmp_rcv | grep -U8 '^ *43\>' goto error; } 38 if (!pskb_pull(skb, sizeof(*icmph))) goto error; icmph = icmp_hdr(skb); 43 ICMPMSGIN_INC_STATS_BH(net, icmph->type); /* * 18 is the highest 'known' ICMP type. Anything else is a mystery * * RFC 1122: 3.2.2 Unknown ICMP messages types MUST be silently * discarded. */ 50 if (icmph->type > NR_ICMP_TYPES) goto error; $ perf probe icmp_rcv:43 'type=icmph->type' (2) $ cat trace-icmp.py [...] def trace_begin(): print "in trace_begin" def trace_end(): print "in trace_end" def probe__icmp_rcv(event_name, context, common_cpu, common_secs, common_nsecs, common_pid, common_comm, __probe_ip, type): print_header(event_name, common_cpu, common_secs, common_nsecs, common_pid, common_comm) print "__probe_ip=%u, type=%u\n" % \ (__probe_ip, type), [...] (3) $ perf record -a -D -e probe:icmp_rcv -o - | \ perf script -i - -s trace-icmp.py Thanks to Peter Zijlstra for pointing how to do it.
