drm/i915/bdb: Fix version check
With patch "drm/i915/vbt: Fix backlight parsing for VBT 234+" the size of bdb_lfp_backlight_data structure has been increased, causing if-statement in the parse_lfp_backlight function that comapres this structure size to the one retrieved from BDB, always to fail for older revisions. This patch calculates expected size of the structure for a given BDB version and compares it with the value gathered from BDB. Tested on Chromebook Pixelbook (Nocturne) (reports bdb->version = 221) Fixes: d381baad29b4 ("drm/i915/vbt: Fix backlight parsing for VBT 234+") Tested-by: Lukasz Majczak <lma@semihalf.com> Signed-off-by: Lukasz Majczak <lma@semihalf.com> Reviewed-by: José Roberto de Souza <jose.souza@intel.com> Signed-off-by: José Roberto de Souza <jose.souza@intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20210930134606.227234-1-lma@semihalf.com
