[PATCH 07/26] habanalabs: use dev_dbg() when hl_mmap_mem_buf_get() fails

From: Oded Gabbay
Date: Thu Dec 08 2022 - 10:14:28 EST


From: Tomer Tayar <ttayar@xxxxxxxxx>

As hl_mmap_mem_buf_get() is called also from IOCTLs which can have a
bad handle from user, modify the print for "no match to handle" to use
dev_dbg().
Calls to this function which are not dependent on user, already have an
error print when the function fails.
