Jonathan Cameron 52615d4783 staging:iio:Documentation generic_buffer.c update to new abi for buffers + misc fixes
Trivial space before newline fix incorporated.

Additional fixes related to handling of sign extension and shifted
data.

Jonathan Cameron d96d1337e3 staging:iio: Add infrastructure for irq_chip based triggers
V3: Get rid of separate interrupt pool. This is well handled
    by irq_get_descs and irq_free_descs.  Two functions I simply
    wasn't aware of previously.  Thus the allocation for a given
    trigger is now handled by core code rather than us reinventing
    the wheel.

V2: Stop silly name duplication.
    Move pool handling to industrialio-trigger as that is the only user.
    Changed over to using irq_modify_status rather than the arm
    specific set_irq_flags as per Thomas Gleixner's suggestion.

This device actually has a pair of interrupts. The code basically ignores

Julia Lawall 311fda8e8b drivers/staging/cptm1217/clearpad_tm1217.c: Correct call to input_free_device
This code is in a loop that currently is only executed once.  Because of
this property, the first block of code is currently actually correct.
Nevertheless, the comments associated with the code suggest that the loop
is planned to take more than one iteration in the future, and thus this
patch is made with that case in mind.

In the first block of code, there is currently an immediate abort from the
function.  It is changed to jump to the error handling code at fail, to be
able to unregister and free the resources allocated on previous iterations.

In the second block of code, the input_dev for the current iteration has
been allocated, but has not been registered.  It has also not been stored
in ts->cp_input_info[i].input.  Thus on jumping to fail, it will not be
freed.  In this case, we want to free, but not unregister, so the free for
this most recently allocated resource is put before the jump.

A simplified version of the semantic match that finds this problem is:
