[PATCH] HID: usbhid: Use seq_buf_putc() in three functions

[Markus Elfring]

From: Markus Elfring <elfring@xxxxxxxxxxxxxxxxxxxxx>

A single space character should occasionally be put into a sequence buffer.
Thus use the function “seq_buf_putc” in these implementations.

The source code was transformed by using the Coccinelle software.
