Subject: [PATCH] I2C: Separate non-i2c hwmon drivers from i2c-core (7/9)
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=5071860aba7fc69279ab822638ed2c2e4549f9fd;p=openwrt%2Fstaging%2Fblogic.git

[PATCH] I2C: Separate non-i2c hwmon drivers from i2c-core (7/9)

Kill normal_isa in header files, documentation and all chip drivers, as
it is no more used.

normal_i2c could be renamed to normal, but I decided not to do so at the
moment, so as to limit the number of changes. This might be done later
as part of the i2c_probe/i2c_detect merge.
