[PATCH 2/2] ALSA: hda: Improve local variable data type in print_device_list()

[Thorsten Blum <thorsten.blum@linux.dev>]

Use 'unsigned int' instead of 'int' for the local variable 'devlist_len'
because snd_hda_get_devices() returns an 'unsigned int' and the length
cannot be negative. Update the print format specifier and the if
condition accordingly.

Reformat calling snd_hda_codec_read() to fit in a single line while
we're at it.
