Wentao Liang bc7fe1a879 gpio: stmpe: Check return value of stmpe_reg_read in stmpe_gpio_irq_sync_unlock 
commit b9644fbfbc upstream.

The stmpe_reg_read function can fail, but its return value is not checked
in stmpe_gpio_irq_sync_unlock. This can lead to silent failures and
incorrect behavior if the hardware access fails.

This patch adds checks for the return value of stmpe_reg_read. If the
function fails, an error message is logged and the function returns
early to avoid further issues.

Fixes: b888fb6f2a ("gpio: stmpe: i2c transfer are forbiden in atomic context")
