2011-12-08Staging: bcm: Alter return value for copy_to/from_user() to "return -EFAULT" ↵Kevin McKinney
when an error occurs. In this clean up patch, I altered functions: copy_to/ from_user() to return -EFAULT when an error occurs. I also replaced break statements when an error occurs from copy_to/from_user() with direct returns of -EFAULT.

remove white space, IOCTL_BCM_NVM_WRITE. This is a clean up patch for IOCTL_BCM_NVM_WRITE that replaces the assignment of the Status variable with direct returns of the error code, replaces the break statements with direct returns, and removes a white space.

2011-12-08Staging: bcm: Fix double free of 'pReadData' in IOCTL_BCM_NVM_WRITE.Kevin McKinney
This patch fixes a memory error in ioctl, IOCTL_BCM_NVM_WRITE. While copying data to user space, if an error occurs, pReadData is freed. Then, at the end of the ioctl, pReadData was being freed again. Signed-off-by: Kevin McKinney <klmckinney1@gmail.com> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>

2011-12-08staging:iio: Fix scan mask updateLars-Peter Clausen
When updating the scan mask we have to check the actual scan mask for if the channel is already enabled, not the matching scan mask from the available scan masks. The bit will already be set there and as a result the actual scan mask will not get updated and the channel stays disabled. Also fix the return value of iio_scan_el_store which would return 1 instead of the number of bytes written if the channel was already active in the scan mask.

2011-12-08staging:iio: Fix sw_ring memory corruptionLars-Peter Clausen
The sw_ring does not properly handle the case where the write pointer already has wrapped around, the read pointer has not and the remaining buffer space at the end is enough to fill the read buffer: +-----------------------------------+ | | |##data##| | +-----------------------------------+ write_p read_p In this case the current code will copy all available data to the buffer and as a result will write beyond the bounds of the buffer and cause a memory corruption. To address this issue this patch adds code to calculate the available buffer space and makes sure that the number of bytes to copy does not exceed this number. This allows the code which copies the data around to be simplified as it only has to consider two cases: Read wraps around and read does not wrap around.
