Date: Mon, 14 Sep 2015 20:42:53 +0530 From: Sudip Mukherjee <sudipm.mukherjee@...il.com> To: Thomas Dahlmann <dahlmann.thomas@...or.de>, Felipe Balbi <balbi@...com>, Greg Kroah-Hartman <gregkh@...uxfoundation.org> Cc: linux-kernel@...r.kernel.org, linux-geode@...ts.infradead.org, linux-usb@...r.kernel.org, Sudip Mukherjee <sudipm.mukherjee@...il.com> Subject: [PATCH 06/16] usb: gadget: amd5536udc: remove unnecessary conditions The condition checking for irq_registered, regs, mem_region and active are not required as this is the remove function. And we are in the remove means that probe was successful and they can never be NULL at this point of code. It was required in the original code as the remove function was part of the error handler of probe function.
