cypto: mediatek - fix leaks in mtk_desc_ring_alloc

2020-10-29T08:55:03+00:00

[ Upstream commit 228d284aac61283cde508a925d666f854b57af63 ]

In the init loop, if an error occurs in function 'dma_alloc_coherent',
then goto the err_cleanup section, after run i--,
in the array ring, the struct mtk_ring with index i will not be released,
causing memory leaks

headers: separate linux/mod_devicetable.h from linux/platform_device.h

2018-07-07T15:52:26+00:00

At over 4000 #includes,  is the 9th most
#included header file in the Linux kernel.  It does not need
, so drop that header and explicitly add
 to source files that need it.

   4146 #include 

After this patch, there are 225 files that use ,
for a reduction of around 3900 times that 
does not have to be read & parsed.

    225 #include 

This patch was build-tested on 20 different arch-es.

It also makes these drivers SubmitChecklist#1 compliant.
