ts5x00: bump to Linux 3.17
The support for the TS-5400 platform is mainlined since Linux 3.17. This commit removes the outdated support patch and bumps the kernel headers (and thus Linux) to 3.17.x. Signed-off-by: Vivien Didelot <vivien.didelot@savoirfairelinux.com> Signed-off-by: Peter Korsgaard <peter@korsgaard.com>

Subject: [PATCH] x86: (ts5500) add board support for TS-5400
|
||||
|
||||
This patch extends the TS-5500 board support to identify the compatible
|
||||
TS-5400 Single Board Computer (ID 0x40).
|
||||
|
||||
It also adds a new "name" sysfs attribute for more human readable
|
||||
identification, actually printing "TS-5500" or "TS-5400".
