+Subject: [PATCH 1/2] wifi: ath11k: fix wrong usage of resource_size() causing
+ firmware panic
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+On converting to the of_reserved_mem_region_to_resource() helper with
+commit 900730dc4705 ("wifi: ath: Use
+of_reserved_mem_region_to_resource() for "memory-region"") a logic error
+was introduced in the ath11k_core_coldboot_cal_support() if condition.
+
+The original code checked for hremote_node presence and skipped
+ath11k_core_coldboot_cal_support() in the other switch case but now
+everything is driven entirely on the values of the resource struct.
+
+resource_size() (in this case) is wrongly assumed to return a size of
+zero if the passed resource struct is init to zero. This is not the case
+as a resource struct should be always init with correct values (or at
+best set the end value to -1 to signal it's not configured)
+(the return value of resource_size() for a resource struct with start
+and end set to zero is 1)
+
+On top of this, using resource_size() to check if a resource struct is
+initialized or not is generally wrong and other measure should be used
+instead.
+
+To better handle this, use the DEFINE_RES macro to initialize the
+resource struct and set the IORESOURCE_UNSET flag by default.
+
+Replace the resource_size() check with checking for the resource struct
+flags and check if it's IORESOURCE_UNSET.
+
+This change effectively restore the original logic and restore correct
+loading of the ath11k firmware (restoring correct functionality of
+Wi-Fi)
