From f42f79af16ce2e8fff49ea9ba4949d3abdd6f26f Mon Sep 17 00:00:00 2001 From: Suman Anna Date: Wed, 16 Sep 2015 19:29:18 -0500 Subject: [PATCH] remoteproc: fix memory leak of remoteproc ida cache layers The remoteproc core uses a static ida named rproc_dev_index for assigning an automatic index number to a registered remoteproc. The ida core may allocate some internal idr cache layers and ida bitmap upon any ida allocation, and all these layers are truely freed only upon the ida destruction. The rproc_dev_index ida is not destroyed at present, leading to a memory leak when using the remoteproc core as a module and atleast one rproc device is registered and unregistered. Fix this by invoking ida_destroy() in the remoteproc core module exit.
