From d0a40174efb0b9d232ccd1cf127cb90a2120f55b Mon Sep 17 00:00:00 2001 From: Jason Gunthorpe Date: Sat, 5 Oct 2013 11:40:19 -0600 Subject: [PATCH] tpm: Remove redundant dev_set_drvdata TPM drivers should not call dev_set_drvdata (or aliases), only the core code is allowed to call dev_set_drvdata, and it does it during tpm_register_hardware. These extra sets are harmless, but are an anti-pattern that many drivers have copied.
