Wolfram Sang 4e75e222d3 i2c: smbus: fix NULL function pointer dereference ... [ Upstream commit 91811a31b6 ] Baruch reported an OOPS when using the designware controller as target only. Target-only modes break the assumption of one transfer function always being available. Fix this by always checking the pointer in __i2c_transfer. Reported-by: Baruch Siach <baruch@tkos.co.il> Closes: https://lore.kernel.org/r/4269631780e5ba789cf1ae391eec1b959def7d99.1712761976.git.baruch@tkos.co.il Fixes: 4b1acc4333 ("i2c: core changes for slave support") [wsa: dropped the simplification in core-smbus to avoid theoretical regressions] Signed-off-by: Wolfram Sang <wsa+renesas@sang-engineering.com> Tested-by: Baruch Siach <baruch@tkos.co.il> Signed-off-by: Sasha Levin <sashal@kernel.org>		2024-05-02 16:29:32 +02:00
