driver core: Convert some drivers to CLASS_ATTR_STRING

2010-03-08T01:04:48+00:00

Convert some drivers who export a single string as class attribute
to the new class_attr_string functions. This removes redundant
code all over.

driver-core: Add attribute argument to class_attribute show/store

2010-03-08T01:04:48+00:00

Passing the attribute to the low level IO functions allows all kinds
of cleanups, by sharing low level IO code without requiring
an own function for every piece of data.

Also drivers can extend the attributes with own data fields
and use that in the low level function.

This makes the class attributes the same as sysdev_class attributes
and plain attributes.

This will allow further cleanups in drivers.

Full tree sweep converting all users.

lkdtm: add debugfs access and loosen KPROBE ties

2010-03-06T19:26:32+00:00

Add adds a debugfs interface and additional failure modes to LKDTM to
provide similar functionality to the provoke-crash driver submitted here:

  http://lwn.net/Articles/371208/

Crashes can now be induced either through module parameters (as before)
or through the debugfs interface as in provoke-crash.

The patch also provides a new "direct" interface, where KPROBES are not
used, i.e., the crash is invoked directly upon write to the debugfs
file. When built without KPROBES configured, only this mode is available.

drivers/misc/iwmc3200top/main.c: eliminate useless code

2010-03-06T19:26:32+00:00

The variable priv is initialized twice to the same (side effect-free)
expression.  Drop one initialization.

A simplified version of the semantic match that finds this problem is:
(http://coccinelle.lip6.fr/)

// 
@forall@
idexpression *x;
identifier f!=ERR_PTR;
@@

x = f(...)
... when != x
(
x = f(...,<+...x...+>,...)

* x = f(...)
)

MFGPT: move clocksource menu

2010-03-06T19:26:28+00:00

Move the CS5535 MFGPT hrtimer kconfig option to be with the other MFGPT
options.  This makes it easier to find and also removes it from the main
"Device Drivers" menu, where it should not have been.

bitops: rename for_each_bit() to for_each_set_bit()

2010-03-06T19:26:23+00:00

Rename for_each_bit to for_each_set_bit in the kernel source tree.  To
permit for_each_clear_bit(), should that ever be added.

The patch includes a macro to map the old for_each_bit() onto the new
for_each_set_bit().  This is a (very) temporary thing to ease the migration.

iwmc3200top: simplify imwct_tx

2009-12-23T22:13:32+00:00

1. remove address argument since we use same address IWMC_SDIO_DATA_ADDR in
    all cases
2. add __iwmct_tx - non locking tx function for already locked contexts

iwmc3200top: clean up fw_download

2009-12-23T22:13:31+00:00

1. removed redundant NULL-pointers checks in iwmct_fw_load
as release_firmware and kfree are NULL pointer friendly
2. remove redundant memset of the parser since the structure
is fully initialized in iwmct_fw_parser_init function
