Subject: [PATCH] mailbox: qcom-ipcc: fix incorrect num_chans counting
Date: Wed, 2 Aug 2023 09:52:22 -0400 [thread overview]
Message-ID: <20230802135222.30754-1-jonathan@marek.ca> (raw)
Breaking out early when a match is found leads to an incorrect num_chans
value when more than one ipcc mailbox channel is used by the same device.
Fixes: e9d50e4b4d04 ("mailbox: qcom-ipcc: Dynamic alloc for channel arrangement")
