[PATCH] tpm: select ANON_INODES for proxy driver

From: Arnd Bergmann
Date: Thu Apr 28 2016 - 06:47:10 EST


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.
