can: mark expected switch fall-throughs
In preparation to enabling -Wimplicit-fallthrough, mark switch cases where we are expecting to fall through. This patch fixes the following warnings: drivers/net/can/peak_canfd/peak_pciefd_main.c:668:3: warning: this statement may fall through [-Wimplicit-fallthrough=] drivers/net/can/spi/mcp251x.c:875:7: warning: this statement may fall through [-Wimplicit-fallthrough=] drivers/net/can/usb/peak_usb/pcan_usb.c:422:6: warning: this statement may fall through [-Wimplicit-fallthrough=] drivers/net/can/at91_can.c:895:6: warning: this statement may fall through [-Wimplicit-fallthrough=] drivers/net/can/at91_can.c:953:15: warning: this statement may fall through [-Wimplicit-fallthrough=] drivers/net/can/usb/peak_usb/pcan_usb.c: In function ‘pcan_usb_decode_error’: drivers/net/can/usb/peak_usb/pcan_usb.c:422:6: warning: this statement may fall through [-Wimplicit-fallthrough=] if (n & PCAN_USB_ERROR_BUS_LIGHT) { ^ drivers/net/can/usb/peak_usb/pcan_usb.c:428:2: note: here case CAN_STATE_ERROR_WARNING: ^~~~ Warning level 3 was used: -Wimplicit-fallthrough=3 This patch is part of the ongoing efforts to enabling -Wimplicit-fallthrough. Notice that in some cases spelling mistakes were fixed. In other cases, the /* fall through */ comment is placed at the bottom of the case statement, which is what GCC is expecting to find.
