Subject: [PATCH 02/12] iwlwifi: mvm: pass the clock type to iwl_mvm_get_sync_time()
Date: Sat, 12 Jun 2021 14:32:35 +0300	[thread overview]
Message-ID: <iwlwifi.20210612142637.093f6660e69b.Ifd2328ac2130269f729c9c1bceec44ba01d79e88@changeid> (raw)
In-Reply-To: <20210612113245.691117-1-luca@coelho.fi>

From: Luca Coelho <luciano.coelho@intel.com>

Allow the caller to pass the clock type to iwl_mvm_get_sync_time() so
callers with different needs can decide whether to use boottime or
realtime.

Signed-off-by: Luca Coelho <luciano.coelho@intel.com>
