In my commit history top commits look like so:
1ccb0058e833d9765a3a1de2816fd408dde82305 Merge branch 'master' of https://github.com/...
d462898e3a1dbd979b38bcec6d45991da0bca1e7 Add one cool feature
7e2f382e89448b7239b45f73f3b5be360435a0e6 Fix code styles
ce6b7f9ce11e06347e05aec4bfb21fea6b3b5b37 Add one cool feature
I want to combine Add one cool feature
, Fix code styles
and Add one cool feature
into one commit and then merge back to master branch. What is the correct way to do this?
