The driver overrides the error codes returned by platform_get_irq() to
-ENODEV, so if it returns -EPROBE_DEFER, the driver will fail the probe
permanently instead of the deferred probing. Switch to propagating the
error codes upstream.

it will print an error message by itself when platform_get_irq()
goes wrong. so don't need dev_err() in here again.

'PTR_ERR(p) == -E*' is a stronger condition than IS_ERR(p).
Hence, IS_ERR(p) is unneeded.
The semantic patch that generates this commit is as follows:
// <smpl>
@@
expression ptr;
constant error_code;
@@
-IS_ERR(ptr) && (PTR_ERR(ptr) == - error_code)
+PTR_ERR(ptr) == - error_code
// </smpl>

Static structure synquacer_i2c_ops, of type i2c_adapter, is only used
when it is copied into a field of another structure. It is not itself
modified. Hence make it const to protect it from unintended
modification.

The I2C host driver for SynQuacer fails to populate the of_node and
ACPI companion fields of the struct i2c_adapter it instantiates,
resulting in enumeration of the subordinate I2C bus to fail.
