[PATCH 0/1 v2 ] ipmi: Setting OS name as Linux in BMC

[Srinivas_G_Gowda]

v2 patch - moving the code to ipmi_msghandler. Called soon after BMC is
registered by the driver.

There is an option in IPMI spec using which BMC can be made aware
of the OS name that it is talking to.
IPMI_Spec-IPMI2_0E4_061209  -  ref - 22.14a ,  .Set System Info.

This patch will update the OS name as "Linux" in BMC during
IPMI Driver initialization. In the current patch declaration of
the OS name is done only for the Volatile param.
