video: irq: Remove IRQF_DISABLED

2011-10-03T15:52:22Z

Since commit [e58aa3d2: genirq: Run irq handlers with interrupts disabled], We run all interrupt handlers with interrupts disabled and we even check and yell when an interrupt handler returns with interrupts enabled (see commit [b738a50a: genirq: Warn when handler enables interrupts]). So now this flag is a NOOP and can be removed. Signed-off-by: Yong Zhang Acked-by: David Brown Signed-off-by: Florian Tobias Schandinat

ARM: pxafb: Fix access to nonexistent member of pxafb_info

2011-04-12T15:07:42Z

In case CONFIG_FB_PXA_OVERLAY is not defined, the pxafb_freq_transition() function tests nonexistent member of pxafb_info (since the member is not part of the structure). Fix this by wraping the test in ifdef, even if I don't really like how the code looks now. The check doesn't have to happen if overlays are disabled at all as the check is always true then.

ARM: pxafb: don't disable controller on cpufreq transition if overlay in use

2011-03-16T09:44:58Z

It's not safe to disable controller if overlay(s) is enabled (results in system hang). So we avoid to disable controller in this case. Userspace should choose proper governor to avoid freq changing when overlay is in use, otherwise LCD may blink. Signed-off-by: Vasily Khoruzhick Signed-off-by: Eric Miao

ARM: pxafb: fix typo in ypos assignment

ARM: pxafb: fix plane Z-ordering problem

2011-03-16T09:37:27Z

pxafb_overlay_init is not right place to change Z-ordering, move it to main plane initialization. Signed-off-by: Vasily Khoruzhick Signed-off-by: Eric Miao

ARM: pxafb: rework pxafb overlay memory management

2011-03-16T09:37:03Z

PXAFB overlay memory management is something messy: - it allocates memory dynamically on open/release, and it results in memory allocation failure after ~1h of uptime (system does not have 115k of physically contiguous memory) - in release callback it tries to free memory even if it was not allocated. Also driver touches FDADR1 on main plane reconfiguration, and it can cause problems if overlay1 is enabled. This patch attempts to fix those issues. Patch is based on Russell King's work.

[ARM] pxafb: fix building issue of incorrect reference

2009-12-29T06:11:27Z

Commit "d2a34c1 drivers/video: Move dereference after NULL test" introduced a build error of "fbi->dev->platform_data->smart_update" being unknown type to the compiler, fix this by removing the unnecessary test of 'fbi'. Cc: Julia Lawall Signed-off-by: Eric Miao

drivers/video: Move dereference after NULL test

2009-12-16T15:20:01Z

If the NULL test on fbi is needed, then the dereference should be after the NULL test. A simplified version of the semantic match that detects this problem is as follows (http://coccinelle.lip6.fr/): // @match exists@ expression x, E; identifier fld; @@ * x->fld ... when != \(x = E\|&x\) * x == NULL // Signed-off-by: Julia Lawall Cc: Krzysztof Helt Cc: Eric Miao Cc: Daniel Mack Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds
