6.6-stable review patch. If anyone has any objections, please let me know.
------------------
From: Mauro Carvalho Chehab <mchehab+huawei@xxxxxxxxxx>
[ Upstream commit 9883a4d41aba7612644e9bb807b971247cea9b9d ]
fepriv->auto_sub_step is unsigned. Setting it to -1 is just a
trick to avoid calling continue, as reported by Coverity.
It relies to have this code just afterwards:
if (!ready) fepriv->auto_sub_step++;
Simplify the code by simply setting it to zero and use
continue to return to the while loop.
Fixes: 1da177e4c3f4 ("Linux-2.6.12-rc2")
