Casting and anding with 0xff is unnecessary in hvc_dcc_put_chars() since buf is already a char[]. __dcc_get_char() can't return an int less than 0 since it only returns a char. Simplify the if statement in hvc_dcc_get_chars() to take this into account. Cc: Daniel Walker <dwalker@codeaurora.org> Signed-off-by:
