debugfs: Pass bool pointer to debugfs_create_bool() 2015-10-04T10:36:07+00:00 Viresh Kumar viresh.kumar@linaro.org 2015-09-26T22:04:07+00:00 621a5f7ad9cd1ce7933f1d302067cbd58354173c Its a bit odd that debugfs_create_bool() takes 'u32 *' as an argument, when all it needs is a boolean pointer. It would be better to update this API to make it accept 'bool *' instead, as that will make it more consistent and often more convenient. Over that bool takes just a byte. That required updates to all user sites as well, in the same commit updating the API. regmap core was also using debugfs_{read|write}_file_bool(), directly and variable types were updated for that to be bool as well.

uwb: Remove umc bus legacy suspend/resume support 2015-03-18T16:27:03+00:00 Lars-Peter Clausen lars@metafoo.de 2015-03-15T17:03:00+00:00 c5b68807c6563bf3882c94268ca09198d2e574ae There are currently no umc drivers implementing suspend/resume, so remove the legacy suspend/resume support from the framework.
