[PATCH] i2c: Handle i2c_add_adapter failure in i2c algorithm drivers
Content-Disposition: inline; filename=i2c-algo-error-handling-fix.patch It is possible for i2c_add_adapter() to fail. Several I2C algorithm drivers ignore that fact. This (compile-tested only) patch fixes them. Signed-off-by: Mark M.
