PM: Remove destroy_suspended_device()

2008-04-20T02:10:28Z

After 2.6.24 there was a plan to make the PM core acquire all device semaphores during a suspend/hibernation to protect itself from concurrent operations involving device objects. That proved to be too heavy-handed and we found a better way to achieve the goal, but before it happened, we had introduced the functions device_pm_schedule_removal() and destroy_suspended_device() to allow drivers to "safely" destroy a suspended device and we had adapted some drivers to use them. Now that these functions are no longer necessary, it seems reasonable to remove them and modify their users to use the normal device unregistration instead. Signed-off-by: Rafael J.

[S390] hw_random: allow rng_dev_read() to return hardware errors.

2008-04-17T05:47:02Z

The api for hardware random number generators is currently limited to devices that never fail. If the hardware is registered as a source for random numbers it has to work. This prevents the use of i/o based random number devices where the i/o might fail. Add a check for errors after the read from a hardware random number device. This patch is required to support large random numbers retrieved from the CEX2C cards on System z. Signed-off-by: Ralph Wuerthner Signed-off-by: Martin Schwidefsky Signed-off-by: Heiko Carstens

[HWRNG]: move status polling loop to data_present callbacks

2008-01-10T21:16:16Z

Handle waiting for new random within the drivers themselves, this allows to use better suited timeouts for the individual rngs. Signed-off-by: Patrick McHardy Acked-by: Michael Buesch Signed-off-by: Herbert Xu

Driver core: change misc class_devices to be real devices

2006-12-01T22:51:59Z

This also ment that some of the misc drivers had to also be fixed up as they were assuming the device was a class_device. Signed-off-by: Greg Kroah-Hartman

[PATCH] make more file_operation structs static

2006-07-03T22:26:59Z

Mark the static struct file_operations in drivers/char as const. Making them const prevents accidental bugs, and moves them to the .rodata section so that they no longer do any false sharing; in addition with the proper debug option they are then protected against corruption..
