Thanks for the comments to the last version, hopefully I addressed
them all. Here is another round of the patches.

changes since last version:

- only kfree() in case of errors
- add missing kfree() in pwmchip_remove()
- drop dynamic pwm id support
- fix typos, remove unused variables
- instantiate pwm_base_common in mxs-pwm driver from resources

The following changes since commit b0af8dfdd67699e25083478c63eedef2e72ebd85:

  Linux 3.0-rc5 (2011-06-27 19:12:22 -0700)
