[PATCH 5.10 152/545] pwm: sifive: Dont check the return code of pwmchip_remove()

[Greg Kroah-Hartman]

From: Uwe Kleine-König <u.kleine-koenig@xxxxxxxxxxxxxx>

[ Upstream commit ceb2c2842f3664dcc4e6d8cb317e1e83bb81b1e5 ]

pwmchip_remove() returns always 0. Don't use the value to make it
possible to eventually change the function to return void. Also the
driver core ignores the return value of pwm_sifive_remove().
