tree-wide: convert open calls to remove spaces to skip_spaces() lib function

2009-12-15T16:53:32Z

Makes use of skip_spaces() defined in lib/string.c for removing leading spaces from strings all over the tree. It decreases lib.a code size by 47 bytes and reuses the function tree-wide: text data bss dec hex filename 64688 584 592 65864 10148 (TOTALS-BEFORE) 64641 584 592 65817 10119 (TOTALS-AFTER) Also, while at it, if we see (*str && isspace(*str)), we can be sure to remove the first condition (*str) as the second one (isspace(*str)) also evaluates to 0 whenever *str == 0, making it redundant. In other words, "a char equals zero is never a space". Julia Lawall tried the semantic patch (http://coccinelle.lip6.fr) below, and found occurrences of this pattern on 3 more files: drivers/leds/led-class.c drivers/leds/ledtrig-timer.c drivers/video/output.c @@ expression str; @@ ( // ignore skip_spaces cases while (*str && isspace(*str)) { \(str++;\|++str;\) } | - *str && isspace(*str) ) Signed-off-by: André Goddard Rosa Cc: Julia Lawall Cc: Martin Schwidefsky Cc: Jeff Dike Cc: Ingo Molnar Cc: Thomas Gleixner Cc: "H.

leds: allow led-drivers to use a variable range of brightness values

2009-04-06T15:06:25Z

This patch allows drivers to override the default maximum brightness value of 255. We take care to preserve backwards-compatibility as much as possible, so that user-space ABI doesn't change for existing drivers. LED trigger code has also been updated to use the per-LED maximum.

leds: Remove uneeded strlen calls

2008-10-20T21:37:04Z

There's no need for the additional call to strlen(), we can directly return the value returned by sprintf(). We now return a length value that doesn't include the final '\0', but user space shouldn't bother about it anyway.

leds: Cleanup various whitespace and code style issues

2008-04-24T22:37:42Z

Break the lines which were more than 80 characters into more lines; replace SPACEs with TABs; correct ident at switch-case; change character encoding from ISO-8859-2 to UTF-8. The order of the functions in led-triggers.c changed in order the similar functions can still be together under titles "Used by LED Class", "LED Trigger Interface" and "Simple LED Tigger Interface" as was grouped before when exported with EXPORT_SYMBOL.

leds: Add support for hardware accelerated LED flashing

2008-02-07T09:49:38Z

Extends the leds subsystem with a blink_set() callback function which can be optionally implemented by a LED driver. If implemented, the driver can use the hardware acceleration for blinking a LED. Signed-off-by: Márton Németh Signed-off-by: Richard Purdie
