[ Upstream commit 8503a4b1a24d32e95f3a233062e8f1dc0b2052bd ]

Add device type data for S32G2/S32G3 SoC.

FlexCAN module from S32G2/S32G3 is similar with i.MX SoCs, but interrupt
management is different.

On S32G2/S32G3 SoC, there are separate interrupts for state change, bus
errors, Mailboxes 0-7 and Mailboxes 8-127 respectively.
In order to handle this FlexCAN hardware particularity, first reuse the
'FLEXCAN_QUIRK_NR_IRQ_3' quirk provided by mcf5441x's irq handling
support. Secondly, use the newly introduced
'FLEXCAN_QUIRK_SECONDARY_MB_IRQ' quirk which handles the case where two
separate mailbox ranges are controlled by independent hardware interrupt
lines.

commit 1d22a122ffb116c3cf78053e812b8b21f8852ee9 upstream.

Commit 7fdaf8966aae ("can: ucan: use strscpy() to instead of strncpy()")
unintentionally introduced a one byte out of bound read on strscpy()'s
source argument (which is kind of ironic knowing that strscpy() is meant
to be a more secure alternative :)).

Let's consider below buffers:

  dest[len + 1]; /* will be NUL terminated */
  src[len]; /* may not be NUL terminated */

When doing:

  strncpy(dest, src, len);
  dest[len] = '\0';

strncpy() will read up to len bytes from src.

On the other hand:

  strscpy(dest, src, len + 1);

will read up to len + 1 bytes from src, that is to say, an out of bound
read of one byte will occur on src if it is not NUL terminated. Note
that the src[len] byte is never copied, but strscpy() still needs to
read it to check whether a truncation occurred or not.

This exact pattern happened in ucan.

The root cause is that the source is not NUL terminated. Instead of
doing a copy in a local buffer, directly NUL terminate it as soon as
usb_control_msg() returns. With this, the local firmware_str[] variable
can be removed.

On top of this do a couple refactors:

  - ucan_ctl_payload->raw is only used for the firmware string, so
    rename it to ucan_ctl_payload->fw_str and change its type from u8 to
    char.

  - ucan_device_request_in() is only used to retrieve the firmware
    string, so rename it to ucan_get_fw_str() and refactor it to make it
    directly handle all the string termination logic.
