* ARCH: drivers remove __dev* attributes.Greg Kroah-Hartman2013-01-041-3/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This fixes up all of the smaller arches that had __dev* markings for their platform-specific drivers. CONFIG_HOTPLUG is going away as an option. As a result, the __dev* markings need to be removed. This change removes the use of __devinit, __devexit_p, __devinitdata, __devinitconst, and __devexit from these drivers. Based on patches originally written by Bill Pemberton, but redone by me in order to handle some of the coding style issues better, by hand.

* Blackfin: cpufreq: fix dpm_state_tableJames Cosin2012-10-081-3/+2
| | | | | | | | | | | | This patch fixes an assumption that cclk's initial divisor will always be 1 (or 0 in the register). TSCALE is always initialized on startup with a value of 4 regardless of the inital cclk divisor; so, we can't make the assumption without making lots of other assumptions. The TPERIOD value is set with a value of the current cclk (value / (HZ * TSCALE)) - 1; so, we need to adjust based on this initial frequency and not use cclk's initial divisor for adjusting the tscale.
