The DMA_CH_VALID bit used in the channel index should be masked out before

If the NULL test on buf 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/):
// <smpl>
@match exists@
expression x, E;
identifier fld;
@@
* x->fld
... when != \(x = E\|&x\)
* x == NULL

Fix the link errors if cpu-frequency support is enabled on s3c2410 systems
but there is no CONFIG_S3C2410_IOTIMING set. Fix this by ensuring the
relevant symbols are defined NULL if the code is not being built in.
Fixes the following error:

Add better support for omitting either the card detect or the write
protect GPIOs if the board does not support it. Add the fields
no_wprotect and no_detect to the platform data which when set indicate the
absence of the respective GPIOs.
Note, this also fixes a minor bug where it tries to free IRQ0 if there is
no detect gpio available.

Currently the S5PC100 does not define S3C_PA_NAND, leaving the NAND device
definitions in arch/arm/plat-s3c/dev-nand.c unbuildable. Add a KConfig
entry to select whether this is built.
As backwards compatibility, both the S3C24XX and S3C64XX define the new
configuration in their main Kconfig files until better support for basing
this selection on a per-machine basis can be sorted out.

The pwm hardware only checks the compare register after a decrement,
so the pin never toggles if tcmp = tcnt.
This happens when a very low duty cycle is requested. Fix it by always

Change the hwmon device name to something more generic as this
should be functional for both the s3c24xx and s3c64xx archs.
Since it has yet to have a driver, it is pretty safe to change
as there are no extant users.
Also add the necessary entry in devs.h which seems to have been
missed out at somepoint.

CONFIG_S3C24XX_PWM was defined in arch/arm/plat-s3c24xx/Kconfig but
not used anywhere else as the corresponding makefile used
CONFIG_HAVE_PWM (selected by CONFIG_S3C24XX_PWM) to compile the PWM
driver.
Change the makefile to use CONFIG_S3C24XX_PWM to compile this driver
to ensure it is only build when needed.
