kmemcheck: remove annotations

2017-11-16T02:21:04+00:00

Patch series "kmemcheck: kill kmemcheck", v2. As discussed at LSF/MM, kill kmemcheck. KASan is a replacement that is able to work without the limitation of kmemcheck (single CPU, slow). KASan is already upstream. We are also not aware of any users of kmemcheck (or users who don't consider KASan as a suitable replacement). The only objection was that since KASAN wasn't supported by all GCC versions provided by distros at that time we should hold off for 2 years, and try again. Now that 2 years have passed, and all distros provide gcc that supports KASAN, kill kmemcheck again for the very same reasons. This patch (of 4): Remove kmemcheck annotations, and calls to kmemcheck from the kernel.

drivers/misc/c2port/c2port-duramar2150.c: checking for NULL instead of IS_ERR()

2017-05-09T00:15:10+00:00

c2port_device_register() never returns NULL, it uses error pointers.

drivers: misc: Drop unlikely before IS_ERR(_OR_NULL)

2015-09-29T13:11:40+00:00

IS_ERR(_OR_NULL) already contain an 'unlikely' compiler flag and there is no need to do that again from its callers. Drop it. Signed-off-by: Viresh Kumar Signed-off-by: Jiri Kosina

c2port: convert class code to use bin_attrs in groups

2013-07-24T22:39:05+00:00

Now that attribute groups support binary attributes, use them instead of the dev_bin_attrs field in struct class, as that is going away soon. Cc: Rodolfo Giometti Signed-off-by: Greg Kroah-Hartman

c2port: convert class code to use dev_groups

2013-07-24T22:39:04+00:00

The dev_attrs field of struct class is going away soon, dev_groups should be used instead. This converts the c2port class code to use the correct field. Cc: Rodolfo Giometti Signed-off-by: Greg Kroah-Hartman

misc: c2port: use dev_bin_attrs instead of hand-coding it

2013-07-24T22:39:04+00:00

Classes support a list of default binary attributes, so use that in the c2port driver, instead of hand creating and destroying the file, which is racing with userspace. Bonus is this removes lines of code. Cc: Rodolfo Giometti Signed-off-by: Greg Kroah-Hartman

char/misc: remove CONFIG_EXPERIMENTAL dependencies

c2port: fix bogus Kconfig "default no"

2012-05-07T13:00:19+00:00

Strictly speaking "no" is a valid, but undefined, Kconfig symbol. But what obviously was meant here was "n". While we're touching this Kconfig file also drop the superfluous dependency on C2PORT for C2PORT_DURAMAR_2150. Its Kconfig entry is already wrapped in "if C2PORT" and "endif".
