tpm: select ANON_INODES for proxy driver

arndb · Jarkko Sakkinen · commit a6885a53a3a2 · 2016-06-25T17:26:35.000+03:00
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.
