The above check is necessary. pdbg_init->compress_buff may be NULL when Zlib is unavailable or when pdbg_init->compress_buff allocation fails, in which case we ignore error and continue without compression. > - vfree(pdbg_init->compress_buff); > + vfree(pdbg_init->compress_buff); > } > > int cxgb4_cudbg_collect(struct adapter *adap, void *buf, u32 *buf_size, > -- > 1.8.3.1 >
