The current error exit path if ir_raw_encode_scancode fails is via the
label out_kfree which kfree's an uninitialized pointer txbuf. Fix this
by exiting via a new exit path that does not kfree txbuf. Also exit
via this new exit path for a failed allocation of txbuf to avoid a
redundant kfree on a NULL pointer (to save a bunch of CPU cycles).

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. Please read the Documentation/process/changes.rst file, as it contains the requirements for building and running the kernel, and information about the problems which may result by upgrading your kernel.
