Subject: gpio: pca953x: Fix NBANK calculation for PCA9536

From: Vignesh R <[email protected]>

commit a246b8198f776a16d1d3a3bbfc2d437bad766b29 upstream.

NBANK() macro assumes that ngpios is a multiple of 8(BANK_SZ) and hence results in 0 banks for PCA9536 which has just 4 gpios. This is wrong as PCA9356 has 1 bank with 4 gpios. This results in uninitialized PCA953X_INVERT register. Fix this by using DIV_ROUND_UP macro in NBANK().
