kernel.git/drivers/char/tpm/tpm-dev.c, branch linux-3.18.yHosts the 0x221E linux distro kernel.
https://git.0xinfinity.dev/distro/kernel.git/atom?h=linux-3.18.y2014-01-06T13:37:25Ztpm: Make tpm-dev allocate a per-file structure2014-01-06T13:37:25ZJason Gunthorpe2013-11-26T20:30:45Zurn:sha1:e3302e0d6dcc02f369ecdc01c8392a28f14c0cba
This consolidates everything that is only used within tpm-dev.c
into tpm-dev.c and out of the publicly visible struct tpm_chip.
The per-file allocation lays the ground work for someday fixing the
strange forced O_EXCL behaviour of the current code.

tpm: Pull everything related to /dev/tpmX into tpm-dev.c2014-01-06T13:37:24ZJason Gunthorpe2013-11-26T20:30:40Zurn:sha1:afdba32e2a9ea729a9f9f280dbf6c718773c7ded
CLASS-dev.c is a common idiom for Linux subsystems
This pulls all the code related to the miscdev into tpm-dev.c and makes it
static. The identical file_operation structs in the drivers are purged and the
tpm common code unconditionally creates the miscdev.

[phuewe:
tpm_dev_release is now used only in this file, thus the EXPORT_SYMBOL
can be dropped and the function be marked as static.
It has no other in-kernel users]
