From: Sean Young Date: Tue, 7 Mar 2017 19:13:15 +0000 (-0300) Subject: [media] staging: sir: remove unselectable Tekram and Actisys X-Git-Tag: v4.12-rc1~85^2~210 X-Git-Url: https://git.kernel.dk/?a=commitdiff_plain;h=402e7b63df726c37d3741aeec5d149b409be5143;p=linux-block.git [media] staging: sir: remove unselectable Tekram and Actisys Support for these sir ports is not compiled in by default, it has to be enabled by manually defining LIRC_TEKRAM, LIRC_SIR_ACTISYS_ACT200L or LIRC_SIR_ACTISYS_ACT220L somewhere. This cannot be done from Kconfig at all so remove them from the driver.
