Subject: [PATCH] Fix for AF9015 DVB-T USB2.0 stick
This reverts commitas:
- 02f9cf96df57575acea2e6eb4041e9f3ecd32548
"[media] [PATH,2/2] mxl5007 move loop_thru to attach"
- fe4860af002a4516dd878f7297b61e186c475b35
"[media] [PATH,1/2] mxl5007 move reset to attach"
This is the conclusion after extensive testing,
these two commitas produce:
mxl5007t_soft_reset: 521: failed!
mxl5007t_attach: error -121 on line 907
causing AF9015 DVB-T USB2.0 stick completely unusable.
