Subject: falconide: fix resources reservation (take 2)
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=cb5528ab19ece76be5299b33746ca7d58c187a26;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git

falconide: fix resources reservation (take 2)

* Tell IDE layer to not manage resources by setting
  hwif->mmio flag and request resources in falconide_init().

* Use request_mem_region() for resources reservation.

* Use driver name for resources reservation.

v2:
* Fix missing printk() parameter. (Noticed by Geert Uytterhoeven)
