From: Arnd Bergmann Date: Mon, 16 Nov 2015 14:05:06 +0000 (+0100) Subject: staging/wilc1000: turn enable_irq/disable_irq into callbacks X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=5547c1f09c070f74978f3cb6c74556b3c5d5d09c;p=GitHub%2FLineageOS%2FG12%2Fandroid_kernel_amlogic_linux-4.9.git staging/wilc1000: turn enable_irq/disable_irq into callbacks As a preparation for turning the SDIO side of wilc1000 into a separate module, this removes the last direct caller from the core module into the sdio specific portion. All calls to wilc_sdio_enable_interrupt() and wilc_sdio_disable_interrupt() now go through a function pointer in wilc_hif_func. We also change arguments slightly to pass the device, as we are already touching those lines and the change will be needed later to remove the global variables.
