[PATCH 4.14 112/126] ASoC: intel: skl: Fix pin debug prints

[Greg Kroah-Hartman]

From: Takashi Iwai <tiwai@xxxxxxx>

commit 64bbacc5f08c01954890981c63de744df1f29a30 upstream.

skl_print_pins() loops over all given pins but it overwrites the text
at the very same position while increasing the returned length.
Fix this to show the all pin contents properly.

Fixes: d14700a01f91 ("ASoC: Intel: Skylake: Debugfs facility to dump module config")
