5.13.0-27-generic Compilation issues

[samr-eroad]

Issue:

Outright compilation error for 5.13.0.-27 generic

Error 1:

/home/user/socketcan-linux-5.0/usb-to-can_socketcan/ixx_usb_fd.c:36:25: error: expected declaration specifiers or ‘...’ before string constant 36 | MODULE_SUPPORTED_DEVICE("IXXAT Automation GmbH USB-to-CAN FD"); | ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Noted that the modules.h in (uname -r)/include/linux directory does not have the MODULE_SUPPORTED_DEVICE define anymore

Error 2:

/home/user/socketcan-linux-5.0/usb-to-can_socketcan/ixx_usb_core.c:256:9: error: too few arguments to function ‘can_get_echo_skb’ 256 | can_get_echo_skb(netdev, context->echo_index); | ^~~~~~~~~~~~~~~~

CAN Kernel source got updated. The function signature is now in the form of

unsigned int can_get_echo_skb(struct net_device *dev, unsigned int idx, unsigned int *frame_len_ptr)

Potential Fixes:

Removing the MODULE_SUPPORTED_DEVICE and passing a nullptr for the third (additional) parameter.
