[ Upstream commit 6dd1de91e7a62bfd3878992c1db6e1d443022c76 ]
The LKP robot complains about: drivers/tty/mips_ejtag_fdc.c:1224:31: error: incompatible pointer types passing 'const char *[1]' to parameter of type 'const u8 **' (aka 'const unsigned char **')
Fix this by turning the missing pieces (fetch from kgdbfdc_wbuf) to u8 too. Note the filling part (kgdbfdc_write_char()) already receives and stores u8 to kgdbfdc_wbuf.
