Hi all,

After merging the crypto tree, today's linux-next build (sparc64
defconfig) failed like this:

drivers/char/hw_random/n2-drv.c: In function 'n2rng_probe':
drivers/char/hw_random/n2-drv.c:771:29: error: 'pdev' undeclared (first use in this function); did you mean 'cdev'?
  err = devm_hwrng_register(&pdev->dev, &np->hwrng);
                             ^~~~
                             cdev
drivers/char/hw_random/n2-drv.c:771:29: note: each undeclared identifier is reported only once for each function it appears in

Caused by commit

  3e75241be808 ("hwrng: drivers - Use device-managed registration API")

I applied the following patch for today:
