Subject: [PATCH AUTOSEL 5.2 069/123] isdn: hfcsusb: Fix mISDN driver crash caused by transfer buffer on the stack
Date: Tue, 13 Aug 2019 22:09:53 -0400
Message-ID: <20190814021047.14828-69-sashal@kernel.org> (raw)
In-Reply-To: <20190814021047.14828-1-sashal@kernel.org>

[ Upstream commit d8a1de3d5bb881507602bc02e004904828f88711 ]

Since linux 4.9 it is not possible to use buffers on the stack for DMA transfers.

During usb probe the driver crashes with "transfer buffer is on stack" message.

This fix k-allocates a buffer to be used on "read_reg_atomic", which is a macro
that calls "usb_control_msg" under the hood.
