There are two fixes on the list: [1] and [2]. Perhaps one of those resolves this?

My guess is that either one avoids the crash, but we actually want both of them since the problem is a combination of the two issues.
I think we also need this one on top, to have a va_end() for each return() statement:
--- a/drivers/clk/clkdev.c +++ b/drivers/clk/clkdev.c @@ -193,6 +193,7 @@ vclkdev_alloc(struct clk_hw *hw, const char *con_id, const char *dev_fmt, cla->cl.dev_id = cla->dev_id; }
+ va_end(ap_copy); return &cla->cl;
