X-Git-Url: http://drtracing.org/?a=commitdiff_plain;h=1296fba1a397b173d45534885a0934a7c005d7e3;p=deliverable%2Flinux.git

gpio: etraxfs: fix set register flag

BGPIO_F_UNREADABLE_REG_SET is incorrect, since the set register _is_
readable.  What's really required is BGPIO_F_READ_OUTPUT_REG_SET:
reading the set register reads the set output value.
