spi/rtc-m41t93: Use spi_get_drvdata() for SPI devices
One new offender detected by the recently increased type checking in platform_get_drvdata(): drivers/rtc/rtc-m41t93.c: In function ‘m41t93_remove’: drivers/rtc/rtc-m41t93.c:192: warning: passing argument 1 of ‘platform_get_drvdata’ from incompatible pointer type Use spi_get_drvdata() instead of platform_get_drvdata(), cfr. commit 42fea15d6dc410e62dac6a764142045280624a5b ("spi/rtc-{ds1390,ds3234,m41t94}: Use spi_get_drvdata() for SPI devices") Signed-off-by: Geert Uytterhoeven <geert@linux-m68k.org> Signed-off-by: Grant Likely <grant.likely@secretlab.ca>
