[PATCH v3] Staging: iio: accel: Fixed NULL comparison style

[Bhaktipriya Shridhar]

The variable u8 **rx_p, is a pointer-to-pointer and hence the check
should
be "if (!*rx_p)" and not "if (!rx_p)".
In the earlier version, checkpatch.pl gave the following check, which
was incorrect:
CHECK: Comparison to NULL could be written "!rx_p"
+       if (*rx_p == NULL) {

 Changes in v3:
        - Replaced "if (!rx_p)" with "if (!*rx_p)"
	- Changes are made on the original code
