[PATCH 1/4] drivers/media/dvb: Remove dead Configs
Following flags were checked, but never set anywhere, therefore removing all references from the source code: CONFIG_BAND_SBAND CONFIG_BAND_LBAND CONFIG_STANDARD_DAB CONFIG_STANDARD_DVBT CONFIG_TUNER_DIB0090_P1B_SUPPORT CONFIG_TUNER_DIB0090_CPTURIM_MEMORY FIREFLY_FIRMWARE Signed-off-by: Christian Dietrich ... 14 Jul 2010 09:51

[PATCH 2/4] drivers/media/dvb: Remove undead configs
The following CONFIG_ options are set within the C File, so the blocks will always be selected. For the matter of readability the ifdefs are not nesseccary: CONFIG_BAND_CBAND CONFIG_BAND_UHF CONFIG_BAND_VHF CONFIG_DIB0090_USE_PWM_AGC CONFIG_SYS_ISDBT Signed-off-by: Christian Dietrich <qy03fugy(a)stud.informat... 14 Jul 2010 09:51

[PATCH 0/4] Removing dead code
Hi all! As part of the VAMOS[0] research project at the University of Erlangen we are looking at multiple integrity errors in linux' configuration system. I've been running a check on the drivers/media sourcetree for config Items not defined in Kconfig and found 4 such cases. Sourcecode ... 14 Jul 2010 09:51

[PATCH 5/8] sdhci: Turn host->lock into a mutex
Finally, we can get rid of the host->lock spinlock, and turn it into a mutex. This patch does just this.

[PATCH 8/8] sdhci: Use jiffies instead of a timeout counter

[PATCH 3/8] sdhci: Clear interrupt status register just once
There's no need to clear the interrupt status register bit-by-bit, we can just clear it once. This simplifies irq handler.

[PATCH 7/8] sdhci: Get rid of mdelay()s where it is safe and makes sense
Since we don't run in the atomic context any longer, we can turn mdelay()s into msleep()s. The only place where the driver is still using mdelay() is sdhci_send_command(). There it is possible to use sleepable delays too, but we don't actually want to force rescheduling in a hot path. Sure, we might end up ca... 14 Jul 2010 09:51

[PATCH 1/8] sdhci: Turn timeout timer into delayed work
There is no need for the timeout handler to run in the atomic context, so this patch turns timeout timeout into the delayed work. Note that the timeout handler still grabs an irqsave spinlock, we'll deal with it in a separate patch.

[PATCH 2/8] sdhci: Use work structs instead of tasklets
The driver can happily live without an atomic context and tasklets, so turn the tasklets into the work structs. Tasklets handlers still grab irqsave spinlocks, but we'll deal with it in a separate patch.
