Input: ims-pcu - fix uninitialized use of 'error' in ims_pcu_buffers_alloc()
In case allocation via usb_alloc_coherent() fails in ims_pcu_buffers_alloc(), the function jumps to the exit path without initializing local variable 'error' that is used as return value. Detected by Coverity - CID 1016531. Signed-off-by: Christian Engelmayer <cengelma@gmx.at> Signed-off-by: Dmitry Torokhov <dmitry.torokhov@gmail.com>
