Subject: [PATCH] qmimodem: Fix error path memory leak in gobi
Date: Tue,  7 May 2024 10:33:58 -0500	[thread overview]
Message-ID: <20240507153408.681340-1-steve.schrock@getcruise.com> (raw)

I noticed this leak when I terminated ofonod while gobi was retrying
discovery on an unresponsive QMUX device.

==8257== 20 (16 direct, 4 indirect) bytes in 1 blocks are definitely lost in loss record 31 of 154
