Now we start to see a number of patches applied that are related to debugging the driver. This patch is removed in the coming patches as you start to see the irq handler evolve as I worked through the DMA data corruption issues. Signed-off-by:

When 'dev' allocation fails in ene_probe we jump to error label where we dereference the 'dev'. Fix it by jumping few lines below. Signed-off-by:

Extend the error handling code with operations found in other nearby error handling code. A simplified version of the sematic match that finds this problem is as follows: (http://coccinelle.lip6.fr/) // <smpl> @r exists@ @r@ statement S1,S2,S3; constant C1,C2,C3; @@ *if (...) {... S1 return -C1;} ... *if (...) {... when != S1 return -C2;} ... *if (...) {... S1 return -C3;} // </smpl> Signed-off-by:

Detection class I2C_CLASS_TV_DIGITAL is set by many adapters but no I2C device driver is setting it anymore, which means it can be dropped. I2C devices on digital TV adapters are instantiated explicitly these days, which is much better. Signed-off-by:

When digitizing composite video from a analog videotape source using the TVP5150's first composite input channel, the captured stream exhibits tearing and synchronization problems[1]. It turns out that commit c0477ad9 caused "TV mode" (as opposed to "VCR mode" or "auto-detect") to be forcibly enabled for both composite inputs. According to the chip documentation[2], "TV mode" disables a "chrominance trap" input filter, which appears to be necessary for high-quality video capture from an analog videotape source. [ Commit c7c0b34c subsequently restricted the problem to the first composite input, apparently inadvertently. ] Since any type of composite signal source can be connected to the TVP5150's first composite input, unconditionally forcing "TV mode" isn't correct. There doesn't appear to be a good way for applications to tell the driver what is connected. Fortunately, the TVP5150 has an operating mode auto-detection feature, which, when enabled, should cause the TVP5150 to auto-detect whether it should use "VCR mode" or "TV mode". Enabling operating mode auto-detection improved video capture quality significantly[3]. Therefore, fix this bug by using operating mode auto-detection. (Also, while here, fix a CodingStyle issue.) For those users who may find this patch via a mailing list archive but who are not able to upgrade to a kernel with a fixed driver: the TVP5150's S-Video and second composite input sources have auto-detection enabled, so you may wish to try using those -- if available on your device -- until this fix makes it a downstream distribution near you. 1.

This is a result of last round of debug with Sami R <maesesami@gmail.com>. Thank you Sami very much! The biggest bug I fixed is that, I was clobbering the CIRCFG register after it is setup That wasn't a good idea really And some small refactoring, etc. Tested-by:
