I missed the int->size_t refactoring in f32fcbedbe92 ("tty: hvc: convert
to u8 and size_t"), which causes the newly used ops in 88ead68e764c
("tty: Add SBI debug console support to HVC SBI driver") to fail to
build due to a

linux/drivers/tty/hvc/hvc_riscv_sbi.c:59:15: error: incompatible function pointer types initializing 'ssize_t (*)(uint32_t, const u8 *, size_t)' (aka 'long (*)(unsigned int, const unsigned char *, unsigned long)') with an expression of type 'int (uint32_t, const char *, int)' (aka 'int (unsigned int, const char *, int)') [-Wincompatible-function-pointer-types]
        .put_chars = hvc_sbi_dbcn_tty_put,

Fixes: f32fcbedbe92 ("tty: hvc: convert to u8 and size_t")
Fixes: 88ead68e764c ("tty: Add SBI debug console support to HVC SBI driver")

I now remember Anup pointing this one out, but looks like I forgot about
