85dc2c65e6 misc: echo: Remove unnecessary parentheses and simplify check for zero
Clang warns when multiple pairs of parentheses are used for a single
conditional statement.

drivers/misc/echo/echo.c:384:27: warning: equality comparison with
extraneous parentheses [-Wparentheses-equality]
        if ((ec->nonupdate_dwell == 0)) {
             ~~~~~~~~~~~~~~~~~~~~^~~~
drivers/misc/echo/echo.c:384:27: note: remove extraneous parentheses
around the comparison to silence this warning
        if ((ec->nonupdate_dwell == 0)) {
            ~                    ^   ~
drivers/misc/echo/echo.c:384:27: note: use '=' to turn this equality
comparison into an assignment
        if ((ec->nonupdate_dwell == 0)) {
                                 ^~
                                 =
1 warning generated.

Remove them and while we're at it, simplify the zero check as '!var' is
used more than 'var == 0'.

6e2055a9e5 staging: echo: move to drivers/misc/
The code is clean, there are users of it, so it doesn't belong in
staging anymore, move it to drivers/misc/.
