Subject: [PATCH] tpm: select ANON_INODES for proxy driver
Date: Thu, 28 Apr 2016 12:46:13 +0200 [thread overview]
Message-ID: <1461840382-2996256-1-git-send-email-arnd@arndb.de> (raw)
The newly added vtpmx driver fails to build if CONFIG_ANON_INODES
is disabled:
drivers/char/built-in.o: In function `vtpmx_fops_ioctl':
(.text+0x97f8): undefined reference to `anon_inode_getfile'
This adds a Kconfig 'select' statement to ensure it's always there
when we need it.

Fixes: 794c38e01358 ("tpm: Proxy driver for supporting multiple emulated TPMs")
