* omap1: Fix compile for omap1_bl.cTony Lindgren2010-01-081-2/+0
| | | | | | | | | | | | | | | | Commit 9905a43b made struct backlight_ops const. Omap was setting check_fb dynamically, which caused the following compile error: drivers/video/backlight/omap1_bl.c: In function 'omapbl_probe': drivers/video/backlight/omap1_bl.c:142: error: assignment of read-only variable 'omapbl_ops' Turns out pdata->check_fb is not being used, so just remove it to fix the compile.

* tree-wide: convert open calls to remove spaces to skip_spaces() lib functionAndré Goddard Rosa2009-12-151-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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".

Expose this functionality via the backlight API. Since when used in this configuration the current sink and boost convertor are very tightly coupled with a multi-stage startup for the current sink which overlaps with the boost convertor startup this driver bypasses the regulator API.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch adds support for the new Apple models incorporating an Nvidia chipset. Apple still uses the same protocol as on older models, but the registers moved to a different address. To do this, two sets of functions are added for the Intel/Nvidia chipset models and passed by the DMI_MATCH function. The initial code has been contributed by Hu Gang <hugang@soulinfo.com>. The driver is known to work on MacBook Pro 3, MacBook Pro 4 and MacBook Pro 5. Its known to work with limitations on MacBook 5 / MacBook Air 2. Changing brightness within X doesn't work, if using Nvidia's proprietary graphics driver with no known fix at present. Changing brightness on a text console or using the open-source driver does work. MacBook Pro 5 has a known bug where the initial brightness after bootup is the last recently used brightness (in Mac OSX), while the firmware reports maximum. Impossible to fix.

* fbmem: fix fb_info->lock and mm->mmap_sem circular locking dependencyAndrea Righi2009-04-012-0/+6
| | | | | | | | | | | | | | | | | | Fix a circular locking dependency in the frame buffer console driver pushing down the mutex fb_info->lock. Circular locking dependecies occur calling the blocking fb_notifier_call_chain() with fb_info->lock held. Notifier callbacks can try to acquire mm->mmap_sem, while fb_mmap() acquires the locks in the reverse order mm->mmap_sem => fb_info->lock.

| | | | | | | The corgi backlight driver is really generic code. This rename makes this a lot clearer and completes the partial rename made a while ago. Signed-off-by: Richard Purdie <rpurdie@linux.intel.com>
