Revision 6acbc5a1dab30aa8f7be7bf3852f343f89147ac5 authored by Mahesh Salgaonkar on 20 November 2014, 04:14:36 UTC, committed by Michael Ellerman on 26 November 2014, 22:32:52 UTC
The current HMI event structure is an ABI and carries a version field to accommodate future changes without affecting/rearranging current structure members that are valid for previous versions. The current version check "if (hmi_evt->version != OpalHMIEvt_V1)" doesn't accomodate the fact that the version number may change in future. If firmware starts returning an HMI event with version > 1, this check will fail and no HMI information will be printed on older kernels. This patch fixes this issue.
