[PATCH v5 7/7] i2c: designware: style changes in existing code

Show all headers | View raw

Replaced all the return variables 'r' in the existing
code by 'ret' to make the code easier to read (and
more standard).

Signed-off-by: Luis Oliveira <lolivei@synopsys.com>
---
Changes V4->V5: (Andy Shevchenko)
- Replaced all the old code using "r" as return to "ret". For consistency 
purposes.
