[PATCH] habanalabs: removed seq_file parameter from is_idle asic functions

From: Oded Gabbay
Date: Thu Jul 14 2022 - 02:53:02 EST


From: Dani Liberman <dliberman@xxxxxxxxx>

Change is_idle functions so it would be more usable outside debugfs.

Do this by replacing seq_file parameter with regular string.
