Current AXI GPIO driver checking for interrupt data in suspend and resume path and reporting as error in case of no interrupt connection. As per AXI GPIO IP specification interrupt connection is optional, driver logic is updated in suspend and resume calls by reporting debug message and enable/disable clock in case of no connection.

In case of error, the function devm_platform_ioremap_resource_byname() returns ERR_PTR() and never returns NULL. The NULL test in the return value check should be replaced with IS_ERR(). Fixes: 4195926a ("gpio: Add support for IDT 79RC3243x GPIO controller") Reported-by:

Drop gpio_regmap_set_drvdata() and instead add it to the configuration data passed to gpio_regmap_register(). gpio_regmap_set_drvdata() can't really be used in a race free way. This is because the gpio_regmap object which is needed by _set_drvdata() is returned by gpio_regmap_register(). On the other hand, the callbacks which use the drvdata might already be called right after the gpiochip_add() call in gpio_regmap_register(). Therefore, we have to provide the drvdata early before we call gpiochip_add(). Signed-off-by:

The platform_set_drvdata() call is only useful if we need to retrieve back the private information. Since the driver doesn't do that, it's not useful to have it. If this is removed, we can also just do a direct return on devm_gpiochip_add_data(). We don't need to print that this call failed as there are other ways to log/see this during probe. Signed-off-by:

The handling of the return value from devm_gpiochip_add_data() is a bit redundant. It prints messages on error and success cases. While the success message may be useful, it is more in the area of log spam, and these can be printed with other forms of kernel logging. This change does a direct return with devm_gpiochip_add_data() in the probe function. The platform_set_drvdata() is needed, as this driver uses the stored private date in the PM suspend/resume routines. Signed-off-by:
