[PATCH v2 11/12] i2c: designware: Remove ->disable() callback

From: Andy Shevchenko
Date: Thu Nov 09 2023 - 13:29:06 EST


Commit 90312351fd1e ("i2c: designware: MASTER mode as separated driver")
introduced ->disable() callback but there is no real use for it. Both
i2c-designware-master.c and i2c-designware-slave.c set it to the same
i2c_dw_disable() and scope is inside the same kernel module.

That said, replace the callback by explicitly calling the i2c_dw_disable().
