As explained in the patch description the MMC core code which manages the GPIO inversion can be cleaned up once no driver depends on it anymore (it seems that only one driver is left, but I don't have hardware for it so I can't test it). More details can also be found in my discussion with Linus on this topic: [1] [0] https://marc.info/?l=linux-gpio&m=154609359306731&w=3 [1] https://marc.info/?l=linux-mmc&m=154626524506451&w=3 Martin Blumenstingl (1): mmc: core: don't override the CD GPIO level when "cd-inverted" is set drivers/mmc/core/host.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) -- 2.20.1
