+Subject: [PATCH] lib/boilerplate/iniparser: Allow building with GCC 10.2
+ 2020101
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+Updating to upstream revision f858275f7f307eecba84c2f5429483f9f28007f8.
+Upstream repository is located at [1].
+
+The reason for updating was the following compiler error when trying
+to compile with GCC 10.2 10.2.1 20201016. As it turned out the problem
+was already addressed upstream:
+
+iniparser/iniparser.c: In function ‘iniparser_load’:
+iniparser/iniparser.c:616:13: error: ‘sprintf’ arguments 3, 4 may
+overlap destination object ‘buf’ [-Werror=restrict]
+ 616 | sprintf(tmp, "%s:%s", section, key);
+ | ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+I reviewed especially the API changes. Most of them are cleanups only
+but two things should be pointed out:
+
+ - The type of the size field of struct _dictionary_ changed from int
+ to ssize_t. The only user of this struct is
+ lib/analogy/calibration.c which uses this structure for internal
+ things only. It is never exposed to any public API so updating is
+ OK and fully backward compatible.
+
+ - dictionary_new changed its signature
+ from dictionary_new(int size)
+ to dictionary_new(size_t size).
+ This function is not part of any public API. So updating does not
+ break backward compatibility.
