Subject: [PATCH] staging: pi433: rf69.c: Replace macros READ_REG and WRITE_REG with inline functions setBit rstBit and rmwBit
To increase the readability of the register accesses, the abstraction of the
helpers was increased from simple read and write to set bit, reset bit and
read modify write bit. In addition - according to the proposal from Walter
Harms from 20.07.2017 - instead of marcros inline functions were used.
As a bonus, with this refactoring a lot of lines were shortened a lot. So
some of them now undershoot 80 chars, thus reducing the total number of
complaints of checkPatch.pl in rf69.c.
