The hardware is very old, so the decision was made to remove it altogether since we want to get rid of the old vb1 framework.

This is error prone, and nobody stepped in to convert this driver to that framework. The hardware is very old, so the decision was made to remove it altogether.

So the hflip and vflip - * module options were given a default value of 1 (the correct value for - * upside down mounted models) - * - * 3) Years later I got a bug report from a user with a laptop with stkwebcam, - * where the module was actually mounted the right way up, and thus showed - * upside down under Linux. So now I was facing the choice of 2 options: - * - * a) Add a not-upside-down list to stkwebcam, which overrules the default. - * - * b) Do it like all the other drivers do, and make the default right for - * cams mounted the proper way and add an upside-down model list, with - * models where we need to flip-by-default. - * - * Despite knowing that going b) would cause a period of pain where we were - * building the table I opted to go for option b), since a) is just too ugly, - * and worse different from how every other driver does it leading to - * confusion in the long run.

The hardware is very old, so the decision was made to remove it altogether since we want to get rid of the old vb1 framework.

The hardware is very old, so the decision was made to remove them altogether since we want to get rid of the old vb1 framework.

The hardware is very old, so the decision was made to remove it altogether since we want to get rid of the old vb1 framework.

The hardware is very old, so the decision was made to remove it altogether since we want to get rid of the old vb1 framework. This patch removes the old driver documentation.

The hardware is very old, so the decision was made to remove them altogether since we want to get rid of the old vb1 framework.
