Dan Carpenter f73b389cb9 mfd: wm831x-auxadc: Prevent use after free in wm831x_auxadc_read_irq() 
[ Upstream commit 26783d74cc6a440ee3ef9836a008a697981013d0 ]

The "req" struct is always added to the "wm831x->auxadc_pending" list,
but it's only removed from the list on the success path.  If a failure
occurs then the "req" struct is freed but it's still on the list,
leading to a use after free.

Fixes: 78bb3688ea ("mfd: Support multiple active WM831x AUXADC conversions")
