E.g. two GPIO based buses that share a single SCL line. To synchronize access to the bus the driver might use locking with the help of i2c_lock_operations(). While this works for normal transfers it is not available during initialization. Especially if i2c-algo-bit module is loaded with parameter bit_test it will issue some basic sanity checks that will access the bus without locking. This might interfere badly with concurrent transfers. Even if these are well synchronized via locks. Allow the consumer of an algorithm to override if the bit_test is allowed or not. For this add a new boolean attribute named skip_bit_test to i2c_algo_bit_data. If set the test is not run.

This way there is no need for extra assignment and extra checks when the function is called. Remove assignment of pcf_doAddress() and replace it with a simple function call.

Add spaces around binary operators. Enforce error fixing based on checkpatch.pl output on file. Move 'ret' variable inside for loop. Then check if (ret < 0) goto out. This improves usage of ret variable.
