Subject: [PATCH 0/5] spi: imx: fix use-after-free on unbind
Date: Mon, 23 Mar 2026 11:49:43 +0100 [thread overview]
Message-ID: <20260323104948.844583-1-johan@kernel.org> (raw)
The SPI subsystem frees the controller and any subsystem allocated
driver data as part of deregistration (unless the allocation is device
managed).
This series fixes the IMX driver that got this wrong and then converts
it to use device managed allocation.
Included are also related cleanups for tegre20-slink and the rockchip
driver.
