You need to understand the situation better, about the purpose of the circular polarizer, about why linear polarizing filters are Not used on sophisticated cameras today.
A linear polarizer will work just fine as far as the photo goes. The photo does not care. We used linear filters in the old days (before electronic sensors).
But a linear polarizer runs strong risk of interfering with the DSLR cameras AF and metering functions. They simply are not designed for polarized light.

See this warning from Wikipedia:
See this warning from Tiffen filters:
See this warning from Hoya filters:
Could go on forever, but also read what your camera manual tells you.
For one example, page 236 of Nikon D5300 Reference Manual:
"The D5300 can not be used with linear polarizing filters. Use C-PL or C-PL II circular polarizing filters instead".
This will not convince everyone of course. :)
The one redeeming factor, if you will NOT use the cameras metering or AF functions, then the linear polarizing filter will still work fine.
