2016-11-18i2c: constify i2c_adapter_quirks structuresJulia Lawall
Check for i2c_adapter_quirks structures that are only stored in the quirks field of an i2c_adapter structure. This field is declared const, so i2c_adapter_quirks structures that have this property can be declared as const also.

2013-04-02i2c: Ignore return value of i2c_del_adapter()Lars-Peter Clausen
i2c_del_adapter() always returns 0. So all checks testing whether it will be non zero will always evaluate to false and the conditional code is dead code. This patch updates all callers of i2c_del_mux_adapter() to ignore the return value and assume that it will always succeed (which it will). In a subsequent patch the return type of i2c_del_adapter() will be made void.
