We forget to save the return value of the call to twl_rtc_write_u8(save_control, REG_RTC_CTRL_REG); in 'ret', making the test of 'ret < 0' dead code since 'ret' then couldn't possibly have changed since the last test just a few lines above. It also makes us not detect failures from that specific twl_rtc_write_u8() call. Signed-off-by:

Add support for PMIC8xxx based RTC. PMIC8xxx is Qualcomm's power management IC that internally houses an RTC module. This driver communicates with the PMIC module over SSBI bus. [akpm@linux-foundation.org: cosmetic tweaks] Acked-by:

For each CPU, do the calibration delay only once. For subsequent calls, use the cached per-CPU value of loops_per_jiffy. This saves about 200ms of resume time on dual core Intel Atom N5xx based systems. This helps bring down the kernel resume time on such systems from about 500ms to about 300ms.

Both displays on digsy_mtc board obtain their configuration from microwire EEPROMs which are connected to the SoC over GPIO lines. We need an easy way to access the EEPROMs to write the needed display configuration or to read out the currently programmed configuration. The generic eeprom_93xx46 SPI driver added by previous patch allows EEPROM access over sysfs. Using the simple driver added by this patch we provide used GPIO interface and access control description on the board for generic eeprom_93xx46 driver and spi_gpio driver. Signed-off-by:

Previous behavior allowed only alphabetic prefixes like pr_info to exceed the 80 column line length limit. ath6kl wants to add a digit into the prefix, so allow numbers as well as digits in the <prefix>_<level> printks. <prefix>_<level>_ratelimited and <prefix>_<level>_once and WARN_RATELIMIT and WARN_ONCE may now exceed 80 cols. Add missing <prefix>_printk type for completeness. Signed-off-by:

Some users would like the ability to not emit some of the messages that checkpatch produces. This can make it easier to use checkpatch in other projects and integrate into scm hook scripts. Add command line option to "--ignore" various message types. Add option --show-types to emit the "type" of each message. Categorize all ERROR, WARN and CHK messages with types. Add optional .checkpatch.conf file to store default options. 3 paths are searched for .checkpatch.conf . customized per-tree configurations $HOME user global configuration when per-tree configs don't exist ./scripts lk defaults to override script The .conf file can contain any valid command-line argument and the contents are prepended to any additional command line arguments. Multiple lines may be used, blank lines are ignored, # is a comment. Update "false positive" output for readability.

A common issue with min() or max() is using a cast on one or both of the arguments when using min_t/max_t could be better. Add cast detection to uses of min/max and suggest an appropriate use of min_t or max_t instead. Caveat: This only works for min() or max() on a single line. It does not find min() or max() split across multiple lines. This does find: min((u32)foo, bar); But it does not find: max((unsigned long)foo, bar); Suggested-by: -

We presently define all kinds of notifiers in notifier.h. This is not necessary at all, since different subsystems use different notifiers, they are almost non-related with each other. This can also save much build time. Suppose I add a new netdevice event, really I don't have to recompile all the source, just network related. Without this patch, all the source will be recompiled. I move the notify events near to their subsystem notifier registers, so that they can be found more easily. This patch: It is not necessary to share the same notifier.h. Signed-off-by:

As stated in drivers/mfd/cs5535-mfd.c, the mfd driver exposes the BARs which then make the GPIO, MFGPT, ACPI, etc. all visible to the system. So the dependencies of the MFGPT stuff have changed, and most people expect Kconfig to bring in the necessary dependencies. Without them, the module fails to load and most people don't understand why because the details of the rewrite aren't captured anywhere most people who know to look. This dependency needs to be reflected in Kconfig. Signed-off-by:

Resource definitions that just define start, end and flags = IORESOURCE_MEM or IORESOURCE_IRQ (with start=end) are quite common. So introduce a shortcut for them.
