From mboxrd@z Thu Jan 1 00:00:00 1970 From: jon-hunter@ti.com (Jon Hunter) Date: Tue, 19 Mar 2013 11:35:56 -0500 Subject: [PATCH V4 18/18] ARM: OMAP2+: return -ENODEV if GPMC child device creation fails In-Reply-To: <1363710956-26773-1-git-send-email-jon-hunter@ti.com> References: <1363710956-26773-1-git-send-email-jon-hunter@ti.com> Message-ID: <1363710956-26773-19-git-send-email-jon-hunter@ti.com> To: linux-arm-kernel@lists.infradead.org List-Id: linux-arm-kernel.lists.infradead.org From: Javier Martinez Canillas gpmc_probe_nor_child() calls of_platform_device_create() to create a platform device for the NOR child. If this function fails the value of ret is returned to the caller but this value is zero since it was assigned the return of a previous call to gpmc_cs_program_settings() that had to succeed or otherwise gpmc_probe_nor_child() would have returned before. This means that if of_platform_device_create() fails, 0 will be returned to the caller instead of an appropriate error code.
