Subject: [PATCH] irqchip/mbigen: stop printing kernel addresses
Date:   Tue, 18 Jun 2019 11:22:02 +0800

Precedence: bulk

After commit ad67b74d2469d9b8 ("printk: hash addresses printed with %p"),
it will print "____ptrval____" instead of actual addresses when mbigen
create domain fails,

  Hisilicon MBIGEN-V2 HISI0152:00: Failed to create mbi-gen@(____ptrval____) irqdomain
  Hisilicon MBIGEN-V2: probe of HISI0152:00 failed with error -12

Instead of changing the print to "%px", and leaking kernel addresses,
just remove the print completely.
