video: fbdev: pxafb: Fix "WARNING: invalid free of devm_ allocated data"
commit 2607391882fca37463187e7f2a9c76dec286947e upstream.
'info->modes' got allocated with devm_kcalloc in of_get_pxafb_display.
This gives this error message:
./drivers/video/fbdev/pxafb.c:2238:2-7: WARNING: invalid free of devm_ allocated data
