The skbs for classic CAN and CAN FD frames are allocated with seperate functions: alloc_can_skb() and alloc_canfd_skb(). In order to support CAN FD frames via the rx-offload helper, the driver itself has to allocate the skb (depending whether it received a classic CAN or CAN FD frame), as the rx-offload helper cannot know which kind of CAN frame the driver has received. This patch moves the allocation of the skb into the struct can_rx_offload::mailbox_read callbacks of the the flexcan and ti_hecc driver and adjusts the rx-offload helper accordingly.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
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.
