Subject: [PATCH 2/2] staging: vchiq: Fix bulk transfers on 64-bit builds
Date: Mon,  4 Jan 2021 12:09:28 +0000	[thread overview]
Message-ID: <20210104120929.294063-3-phil@raspberrypi.com> (raw)
In-Reply-To: <20210104120929.294063-1-phil@raspberrypi.com>

The recent change to the bulk transfer compat function missed the fact
the relevant ioctl command is VCHIQ_IOC_QUEUE_BULK_TRANSMIT32, not
VCHIQ_IOC_QUEUE_BULK_TRANSMIT, as any attempt to send a bulk block
to the VPU would have shown.

Fixes: a4367cd2b231 ("staging: vchiq: convert compat bulk transfer")
