thunderbolt: Make priority unsigned in struct tb_path
Clang warns: drivers/thunderbolt/tunnel.c:504:17: warning: implicit truncation from 'int' to bit-field changes value from 5 to -3 [-Wbitfield-constant-conversion] path->priority = 5; ^ ~ 1 warning generated. The priority member in struct tb_path is only ever assigned a positive number: $ rg -n priority drivers/thunderbolt/path.c drivers/thunderbolt/tunnel.c:99: path->priority = 3; drivers/thunderbolt/tunnel.c:308: path->priority = 2; drivers/thunderbolt/tunnel.c:323: path->priority = 1; drivers/thunderbolt/tunnel.c:504: path->priority = 5; Furthermore, that value is only assigned to an unsigned integer in tb_path_activate (the priority member in struct tb_regs_hop).
