Subject: [PATCH 07/26] habanalabs: use dev_dbg() when hl_mmap_mem_buf_get() fails
Date: Thu,  8 Dec 2022 17:13:31 +0200	[thread overview]
Message-ID: <20221208151350.1833823-7-ogabbay@kernel.org> (raw)
In-Reply-To: <20221208151350.1833823-1-ogabbay@kernel.org>

From: Tomer Tayar <ttayar@habana.ai>

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.
