Subject: [PATCH AUTOSEL 6.7 07/19] hwrng: starfive - Fix dev_err_probe return error

From: Jia Jie Ho <jiajie.ho@...rfivetech.com>

[ Upstream commit 2d37b3649c412b3bcecfea932cb677f7a5775b15 ]

Current dev_err_probe will return 0 instead of proper error code if
driver failed to get irq number. Fix the return err code.
