2011-08-29staging: serqt_usb2: remove ssu100 from supported devicesBill Pemberton
The serqt_usb2 driver will not work properly with the ssu100 device even though it claims to support it. The ssu100 is supported by the ssu100 driver in mainline so there is no need to have it claimed by serqt_usb2.

2011-08-29staging/easycap: fix mismatch in easycap_poll() mutex lock-unlockAlexey Khoroshilov
In case if condition (kd != isdongle(peasycap)) becomes true, easycap_poll() returns without releasing easycapdc60_dongle[kd].mutex_video. The patch adds mutex_unlock() before that return.
