regmap: debugfs: Don't bother actually printing when calculating max length

2016-08-26T18:44:48+00:00

commit 176fc2d5770a0990eebff903ba680d2edd32e718 upstream. The in kernel snprintf() will conveniently return the actual length of the printed string even if not given an output beffer at all so just do that rather than relying on the user to pass in a suitable buffer, ensuring that we don't need to worry if the buffer was truncated due to the size of the buffer passed in.

regmap: debugfs: Ensure we don't underflow when printing access masks

2016-08-26T18:44:47+00:00

commit b763ec17ac762470eec5be8ebcc43e4f8b2c2b82 upstream. If a read is attempted which is smaller than the line length then we may underflow the subtraction we're doing with the unsigned size_t type so move some of the calculation to be additions on the right hand side instead in order to avoid this.
