[PATCH v2] ASoC: tas2562: fix deprecated 'shut-down' GPIO always cleared after lookup

[Uday Khare]

In tas2562_parse_dt(), the fallback lookup for the deprecated
"shut-down" GPIO property is broken due to a missing pair of braces.

The code intends to reset sdz_gpio to NULL only when the lookup
returns an error that is not -EPROBE_DEFER (so the driver gracefully
continues without a GPIO). However, without braces the statement:

    tas2562->sdz_gpio = NULL;

falls outside the IS_ERR() check and is executed unconditionally
for every path through the if block, including a successful GPIO
lookup.

This means any device using the deprecated 'shut-down' DT property
will always have sdz_gpio == NULL after probe, making the GPIO
completely non-functional.

Fix this by adding the missing braces to scope the NULL assignment
inside the IS_ERR() branch, matching the pattern already used for
the primary 'shutdown' GPIO lookup above.
