Subject: gpio-wm831x: Use seq_putc() in wm831x_gpio_dbg_show()
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=b5cd7802dd7c10c5be388c8820d8e753f4f8fce7;p=linux.git

gpio-wm831x: Use seq_putc() in wm831x_gpio_dbg_show()

A single character (line break) should be put into a sequence.
Thus use the corresponding function "seq_putc".

This issue was detected by using the Coccinelle software.
