Subject: V4L/DVB (3129): correct FE_READ_UNCORRECTED_BLOCKS
X-Git-Tag: v2.6.16-rc1~663^2~88
X-Git-Url: https://err.no/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=2c3f11b20fc6c41b4d3f64f301f525e35f18b6bc;p=linux-2.6

V4L/DVB (3129): correct FE_READ_UNCORRECTED_BLOCKS

- Make FE_READ_UNCORRECTED_BLOCKS reset the count after each call,
thus returning a momentary value like all other demods do,
instead of an absolute, ever increasing count.
