From a80d0cb6f6addc5a1f3852466fe8d37ca4fe1350 Mon Sep 17 00:00:00 2001 From: Christophe Ricard Date: Thu, 13 Nov 2014 00:30:26 +0100 Subject: NFC: st21nfcb: Remove gpio_irq field in static and dts configuration - phy->gpio_irq is never done out of the request resources. - irq_of_parse_and_map is already done in the i2c core so client->irq is already set when entering in st21nfcb_hci_i2c_of_request_resources - In case of static platform configuration client->irq can be set directly. - It simplifies the code a bit.
