Make the SPI external GPIO expander drivers register themselves at subsys_initcall() time when they're statically linked, and make the SPI core do its driver model initialization earlier so that's safe. SOC-integrated GPIOs are available starting very early -- often before initcalls start to run, or earily in arch_initcall() at latest -- so this improves consistency, letting more subsystems rely on GPIOs being usable by their own subsys_initcall() code.

Make the chip info structure data optional by providing reasonable defaults. Improve corresponding documentation, and highlight the drawback of not providing explicit chipselect control. DMA can determine appropriate dma_burst_size and thresholds automatically so use DMA even if dma_burst_size is not specified. Signed-off-by:

Minor fixes: remove redundant local variable initialization, fix "can not" to what I _think_ is a preferred spelling, output IRQ number if requesting it failed. Signed-off-by:

Add a pin configuration callback for the s3c24xx SPI driver, as there are several options depending on the channel and the chip in use. This is needed as the controller may not have been setup by the initial bootloader and the fact that the SPI controller gets reset over suspend/resume into slave mode but the GPIO function registers do not.

Modify spi_write_then_read() to use one transfer. This speeds up all callers, and is a minor code shrink. Signed-off-by:

binfmt_script and binfmt_misc disallow recursion to avoid stack overflow using sh_bang and misc_bang. It causes problem in some cases: $ echo '#!/bin/ls' > /tmp/t0 $ echo '#!/tmp/t0' > /tmp/t1 $ echo '#!/tmp/t1' > /tmp/t2 $ chmod +x /tmp/t* $ /tmp/t2 zsh: exec format error: /tmp/t2 Similar problem with binfmt_misc. This patch introduces field 'recursion_depth' into struct linux_binprm to track recursion level in binfmt_misc and binfmt_script. If recursion level more then BINPRM_MAX_RECURSION it generates -ENOEXEC. [akpm@linux-foundation.org: make linux_binprm.recursion_depth a uint] Signed-off-by:

This change is Alpha-specific. It adds field 'taso' into struct linux_binprm to remember if the application is TASO. Previously, field sh_bang was used for this purpose. Signed-off-by:

When reporting some complex trailing statements we report only the starting line of the error, that tends to imply the shown line is in error and confuse the reader. As we do know where the actual error is report that line too with an appropriate gap marker where applicable. #ERROR: trailing statements should be on next line #1: FILE: Z202.c:1: + for (pbh = page_buffers(bh->b_page); pbh != bh; + pbh = pbh->b_this_page, key++); #ERROR: trailing statements should be on next line #4: FILE: Z202.c:4: + for (pbh = page_buffers(bh->b_page); [...] + pbh = pbh->b_this_page, key++); Signed-off-by: -

We often see macros which define structure members, these are not complex and necessarily do not have braces or brackets. For example: #define _PLIST_HEAD_INIT(head) \ .prio_list = LIST_HEAD_INIT((head).prio_list), \ .node_list = LIST_HEAD_INIT((head).node_list) Signed-off-by: -

A do without braces '{' may trigger a false possible type 'do' and then this may be interpreted as an external definition of foo(): do foo(); while (bar); Add do to the type exclusions. Fix up tests so we can check for them. Signed-off-by: -

We are currently only reporting syspect indents if the conditional is modified but the indent missmatch could be generated by the body changing, make sure we catch both. Also only report the first line of the body, and more importantly make sure we report the raw copy of the line. Finally report the indent levels to make it easier to understand what is wrong.
