From 61c3f95e0f22fa2d893f7bb3150a7e86ded7ad03 Mon Sep 17 00:00:00 2001 From: Anders Roxell Date: Fri, 8 Feb 2019 13:34:19 +0100 Subject: [PATCH] tpm: i2c_infinion: remove unused input variable 'chip' In both functions release_locality and check_locality, they have a input variable 'struct tpm_chip *chip' that isn't used in the function, so lets remove the variable.
