  "message": "mm/dmapool: allow NULL `pool\u0027 pointer in dma_pool_destroy()\n\ndma_pool_destroy() does not tolerate a NULL dma_pool pointer argument and\nperforms a NULL-pointer dereference.  This requires additional attention\nand effort from developers/reviewers and forces all dma_pool_destroy()\ncallers to do a NULL check\n\n    if (pool)\n        dma_pool_destroy(pool);\n\nOr, otherwise, be invalid dma_pool_destroy() users.\n\nTweak dma_pool_destroy() and NULL-check the pointer there.\n\nProposed by Andrew Morton.\n\nLink: https://lkml.org/lkml/2015/6/8/583\nSigned-off-by: Sergey Senozhatsky \u003csergey.senozhatsky@gmail.com\u003e\nAcked-by: David Rientjes \u003crientjes@google.com\u003e\nCc: Julia Lawall \u003cjulia.lawall@lip6.fr\u003e\nCc: Joe Perches \u003cjoe@perches.com\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n",
