+Subject: [PATCH] UBI: block: Mark init-only symbol as __initdata
+
+ubiblock_param_ops should be marked as __init as it's only used to set
+a driver parameter on insertion time. This commit fixes the following:
+
+  WARNING: drivers/mtd/built-in.o(.text+0x653ac): Section mismatch in
+  reference from the variable ubiblock_param_ops to the function
+  .init.text:ubiblock_set_param()
+
+  The function ubiblock_param_ops() references the function __init
+  ubiblock_set_param(). This is often because ubiblock_param_ops lacks a
+  __init annotation or the annotation of ubiblock_set_param is wrong.
+
+Given gcc errors if the struct is marked const __initdata, this commit
+drops the const mark from it.
