Subject: [PATCH v10 1/3] media: tpg: change char argument to const char
Date: Sun, 5 Jul 2020 19:23:04 +0530 [thread overview]
Message-ID: <20200705135307.27564-2-kgupta@es.iitr.ac.in> (raw)
In-Reply-To: <20200705135307.27564-1-kgupta@es.iitr.ac.in>
Change the argument of type char * to const char * for function
tpg_gen_text().
This function should take in a const char * as opposed to char * as it
does not make changes to the text. This issue was found while passing
the order of colors of tpg generated test image (which is a const char
*) to this function.
