This removes the definition of the offset variable, volatile uint32_t usb_bulk_buffer_offset = 0; which is actually superfluous. This variable, along with its neighbour usb_bulk_buffer_tx, is placed explicitly by the linker script. Its type is defined by the declaration in usb_bulk_buffer.h. There is no need to define it here, and doing so gives the misleading impression that its initial value can be changed by modifying this line! The initialization to zero never actually takes effect, because the variable is not placed in the .data or .bss sections which are initialised by the startup code. The offset and tx variables are both set in set_transceiver_mode before SGPIO streaming is started, so the M0 code does not use them uninitialised.
