commit 4686392c32361c97e8434adf9cc77ad7991bfa81 upstream.

The TX/RX register should not be treated the same way to allow for better
support of tuning. Fix this by using a default initial value for TX.

<title>altera-stapl: altera_get_note: prevent write beyond end of 'key'</title>

[ Upstream commit 3745488e9d599916a0b40d45d3f30e3d4720288e ]

altera_get_note is called from altera_init, where key is kzalloc(33).

When the allocation functions are annotated to allow the compiler to see
the sizes of objects, and with FORTIFY_SOURCE, we see:

In file included from drivers/misc/altera-stapl/altera.c:14:0:
In function ‘strlcpy’,
    inlined from ‘altera_init’ at drivers/misc/altera-stapl/altera.c:2189:5:
include/linux/string.h:378:4: error: call to ‘__write_overflow’ declared with attribute error: detected write beyond size of object passed as 1st parameter
    __write_overflow();
    ^~~~~~~~~~~~~~~~~~

That refers to this code in altera_get_note:

    if (key != NULL)
            strlcpy(key, &amp;p[note_strings +
                            get_unaligned_be32(
                            &amp;p[note_table + (8 * i)])],
                    length);

The error triggers because the length of 'key' is 33, but the copy
uses length supplied as the 'length' parameter, which is always
256. Split the size parameter into key_len and val_len, and use the
appropriate length depending on what is being copied.

Detected by compiler error, only compile-tested.

[ Upstream commit cf01514c5c6efa2d521d35e68dff2e0674d08e91 ]

During device memory memset, the driver allocates and use a CB (command
buffer). To reuse existing code, it keeps a pointer to the CB in two
variables, user_cb and patched_cb. Therefore, there is no need to "put"
both the user_cb and patched_cb, as it will cause an underflow of the
refcnt of the CB.

[ Upstream commit a37e47192dfa98f79a0cd5ab991c224b5980c982 ]

During hard reset we must not write to the device.
Hence avoid halting CoreSight during user context close if it is done
during hard reset.
In addition, we must not re-enable clock gating afterwards as it was
deliberately disabled in the beginning of the hard reset flow.

[ Upstream commit fa4e7fc1386078edcfddd8848cb0374f4af74fe7 ]

xsdfec_poll() is defined as returning 'unsigned int' but the
.poll method is declared as returning '__poll_t', a bitwise type.

Fix this by using the proper return type and using the EPOLL
constants instead of the POLL ones, as required for __poll_t.
