[PATCH 6.1 140/194] misc: mei: client.c: fix problem of return -EOVERFLOW in mei_cl_write

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



6.1-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Su Hui <suhui@xxxxxxxxxxxx>

[ Upstream commit ee6236027218f8531916f1c5caa5dc330379f287 ]

Clang static analyzer complains that value stored to 'rets' is never
read.Let 'buf_len = -EOVERFLOW' to make sure we can return '-EOVERFLOW'.

Fixes: 8c8d964ce90f ("mei: move hbuf_depth from the mei device to the hw modules")
