From 30221b45e02f0be8940debd8ad5690c77d6a97a6 Mon Sep 17 00:00:00 2001 From: Furquan Shaikh Date: Mon, 15 May 2017 14:35:15 -0700 Subject: drivers/spi/spi_flash: Pass in flash structure to fill in probe Instead of making all SPI drivers allocate space for a spi_flash structure and fill it in, udpate the API to allow callers to pass in a spi_flash structure that can be filled by the flash drivers as required. This also cleans up the interface so that the callers can maintain and free the space for spi_flash structure as required.
