Subject: [PATCH 13/14] fbdev: vesafb: fix memory leak in vesafb_probe()
Date: Thu, 14 May 2026 13:54:42 +0530 [thread overview]
Message-ID: <20260514-fbdev-v1-13-b3a2474fa720@cse.iitm.ac.in> (raw)
In-Reply-To: <20260514-fbdev-v1-0-b3a2474fa720@cse.iitm.ac.in>
Since commit 73ce73c30ba9 ("fbdev: Transfer video= option strings to
caller; clarify ownership") the string returned from fb_get_options()
is expected to be freed by the caller. But the string is not freed in
vesafb_probe(). Fix that by freeing the option string after setup.
Fixes: 73ce73c30ba9 ("fbdev: Transfer video= option strings to caller; clarify ownership")
