From 75341b3d358d27f7c22e48bcd92926c49f79e9be Mon Sep 17 00:00:00 2001 From: Serge Semin Date: Thu, 28 May 2020 17:50:47 +0300 Subject: bus: bt1-apb: Use PTR_ERR_OR_ZERO to return from request-regs method Indeed it's more optimal to use the PTR_ERR_OR_ZERO() macro there instead of having two return points.
